When buying fasteners, understanding their material is a very important step. Common material choices include carbon steel and stainless steel, what is the difference between the two? Let's explore this in detail.
Carbon steel and stainless steel are both important categories in steel products and are widely used in various industrial and construction fields. However, they differ significantly in composition, performance and use.
First, what is carbon steel and alloy steel?
Carbon steel: Carbon steel is an iron-carbon alloy with a carbon content of less than 2.11%. In addition to iron and carbon, it also contains limited amounts of silicon, manganese, phosphorus, sulfur and other impurity elements, but does not contain other alloying elements. Carbon steel accounts for about 80% of the total production of steel, because of its low production cost, wide performance, is widely used in construction, Bridges, vehicles, machinery manufacturing and other fields.
Alloy steel: Alloy steel is steel with one or more alloying elements added on the basis of carbon steel, such as chromium, nickel, tungsten, titanium, vanadium, manganese, copper, aluminum, molybdenum and so on. The addition of these elements can significantly improve specific properties of steel, such as increasing hardness, improving corrosion resistance, increasing strength, improving formability and changing weldability. Alloy steel accounts for about 20% of total steel production and is widely used in occasions requiring special properties, such as petrochemical, medical equipment, aerospace and other fields.
Classification of carbon steel and alloy steel
Classification of carbon steel: According to the different carbon content, carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel three categories. Low carbon steel carbon content ≤0.25%, common grades are A3 steel, Q215A steel, Q235 steel, etc., mostly used to manufacture some common structures and parts; Medium carbon steel carbon content is between 0.25% and 0.45%, common grades are 35# steel, 45# steel, etc., suitable for mechanical parts and tools; High carbon steel, with a carbon content of > 0.45%, is rarely used in the manufacture of fasteners because of its high hardness but poor toughness.
Classification of alloy steel: According to the total content of alloying elements, alloy steel can be divided into low alloy steel (total alloy content ≤5%), medium alloy steel (5% < total alloy content ≤10%) and high alloy steel (total alloy content > 10%). Low alloy steel is often used to make some structural parts that require high strength, while medium alloy steel and high alloy steel are used in more demanding environments, such as high temperature, high pressure, strong corrosion and so on.
Three. Characteristics of carbon steel and alloy steel
Characteristics of carbon steel: The performance of carbon steel mainly depends on its carbon content. The higher the carbon content, the strength and hardness will increase correspondingly, while the plasticity, toughness and weldability will decrease. The advantages of carbon steel include good plasticity and weldability, cheap price, easy to smelt and process; The disadvantage is that its strength is relatively low, poor hardenability, low temperature resistance and corrosion resistance are insufficient, and the magnetic conductivity is low, and it is easy to be magnetized in the magnetic field.
Characteristics of alloy steel: By adding different alloying elements, alloy steel can obtain a variety of excellent properties. Its advantages include good comprehensive performance, suitable for special purposes, high strength, high toughness, good hardenability, wear resistance, corrosion resistance, low temperature protection and high temperature protection and non-magnetic; The disadvantage is that the price is high, and the molding process and heat treatment process are complex.
Fourth, the use of carbon steel and alloy steel
Use of carbon steel: Carbon steel is widely used in the manufacture of various building components, containers, boxes, furnace bodies and agricultural machinery and other small-bearing parts. For example, Q215A steel is often used in the manufacture of washers, Q235 steel is suitable for the manufacture of bolts, nuts, screw sleeves, cotter pins and rivets, etc., mainly used in some ordinary products without hardness requirements; The 35# steel and 45# steel belong to the high-quality carbon steel structure, which is mostly used to manufacture 8.8 bolts and 8 nuts and 8.8 hex fasteners.
Use of alloy steel: Alloy steel is usually used for occasions that require high performance, such as parts of transportation vehicles (automobiles, ships, aircraft, etc.), parts of mechanical equipment (machine tools, rockets, missiles, etc.) and various rolling bearings, tools, measuring tools, springs, molds, etc. In special environments, such as high temperature, high pressure and strong corrosion conditions working equipment (such as steam turbines, boilers, chemical equipment, etc.), also made of alloy steel. The alloy steel used to manufacture fasteners mainly includes some high-strength bolts and nuts, such as 30CrMo and 40Cr of 10.9 grade, 35CrMo and 42CrMo of 12.9 grade, etc. These materials are often used in the manufacture of high load bearing bolts, stud bolts, screw sleeves, pins, connecting rod screws, nuts, etc.
In summary, when selecting fastener material, carbon steel or alloy steel can be selected according to the specific use needs. If the application scenario does not have high requirements for the strength and accuracy of the material, and the cost factor needs to be considered, then carbon steel may be a more suitable choice. If the application environment is more severe, especially in the case of high requirements for strength, durability and corrosion resistance, the choice of alloy steel is undoubtedly more appropriate.
Qualified 304 stainless steel is a high-quality material, it should not precipitate heavy metals at any temperature. This means that whether you use this stainless steel product in the cold winter or in the hot summer, there will be no heavy metal ions released into your food or drinking water. However, unqualified stainless steel products may precipitate heavy metal ions in their water under specific conditions, such as acid, alkali and salt. Although temperature has some effect on these processes, the effect is negligible.
Time is the main factor. Therefore, it is not recommended to buy products such as thermos cups and water cups on the ground, because they may not meet the quality standards. In contrast, everyday items such as cutlery, vegetable basins and washbasins can be bought and used with confidence. These items are in contact with water and food for a relatively short time, and most of the dissolved matter or rust is removed during scrubbing. Therefore, their health effects are very weak, and even the amount of heavy metals ingested in a few years is not as much as a plate of stir-fried bracken.
As for the change of 304 stainless steel at different temperatures, it will turn slightly yellow at 150 ° C, significantly yellow at 250 ° C, and seriously yellow at 350 ° C. When the temperature reaches about 400 ° C, the stainless steel will become colored and appear yellow. These problems are not major and are usually caused by the oxidation of iron to iron oxide.
In addition, the color change phenomenon is caused by the formation of oxides of chromium-nickel elements. When you make acidic food with this stainless steel, these oxides may be dissolved and migrate into the food. Therefore, when choosing stainless steel products, it is very important to ensure that they are qualified products that meet the standards.

What is the material inside the hammer? The inside of the broken hammer is made of high chromium alloy. High chromium alloy is a kind of wear-resistant material with excellent anti-wear properties, but its toughness is low and brittle fracture occurs. In order to make the high chromium alloy hammer work normally, the structure of the hammer is generally adopted.
The first is to use a large area hammer to support the high chromium hammer head, and the toughness of the hammer handle supports the huge impact force during the crushing process.
The second is a dual-hydrothermal composite material, The material uses different optimal combinations of chromium, molybdenum, copper, nickel, vanadium, titanium and other alloys and rigorous unique production process, set high chromium alloy casting excellent wear resistance, high temperature oxygen resistance, thermal fatigue resistance (or corrosion resistance) and cast steel good toughness and machinability and one, with a single metal material is difficult to achieve excellent wear resistance and impact resistance of the overall comprehensive performance.
The high chromium wear-resistant hammer is the raw material of the ordinary crusher hammer, which is loaded with heavy elements of chromium metal. The grain is refined after the metamorphic treatment during melting, and the next pouring molding is carried out in the negative pressure state. The high chromium cast iron material used in the head of the hammer has high density, can withstand the larger impact load, and has sufficient anti-wear performance. The hammer handle is made of low alloy steel with good toughness, good toughness and no fracture to ensure normal operation.
High chromium wear-resistant hammer is mainly used to break some stones with high hardness, such as basalt, granite, river pebbles and so on. With the strengthening of the infrastructure construction project, the development trend of mining machinery industry is becoming more and more prosperous, and the crusher equipment has been a relatively rapid comprehensive development, and the amount of the hammer head of the main parts of the crusher has increased.
It is said that in the first World War in 1914, Britain, France and Germany launched a fierce battle, it is not so advanced weapons, the quality of British soldiers rifles is not good, often used after particularly easy to wear, so at that time want to create a new gun, but the material is particularly expensive, the British government is very headache, decided to re-develop a new bore resistant to wear.
This task was given to Brearley, who was a famous metal expert in Britain at that time, when he received the task, he began to study, a long time passed, but Brearley's development work did not make substantial progress, in the corner of the laboratory, all kinds of discarded steel piled up into a hill. Brearley regained his confidence. He decided to clean up the lab for new experiments.
Suddenly, a researcher cried out, "Why is this alloy steel silver shiny, shiny, there is no rust?" "It does not rust, indicating that it is not easily corroded by air, so what is it easily corroded by?" It turned out to be chrome, which Brearley eliminated because it wasn't hard enough to wear out easily. So if you can't do guns, what can you do? It is also the function of waste utilization, and finally made into knives and forks, which is the source of stainless steel.
Brearley's invention of stainless steel in 1916 obtained a British patent and began mass production, so far, from the trash accidentally found stainless steel has become popular around the world, Brearley is also known as the "father of stainless steel."

Does 304 stainless steel pipe have a specific product classification?
Stainless steel pipe is a kind of material widely used in various industrial fields, which has the characteristics of corrosion resistance, high temperature resistance and high strength. In the stainless steel pipe market, according to different uses and specifications, it can be divided into a variety of different types.
First of all, according to the wall thickness to divide, stainless steel pipe can be divided into thin wall pipe and thick wall pipe. Thin-walled tubes are usually used in occasions where smaller pressure or fluid flow is required, such as building decoration, mechanical parts, and so on. The thick wall pipe is suitable for engineering fields under greater pressure or with greater fluid flow, such as petroleum, chemical industry, shipbuilding and so on.
Secondly, according to the different production process, stainless steel pipes can be divided into seamless pipes and welded pipes. Seamless pipe is processed by cold drawing or hot rolling process, with high precision and surface quality. Welded pipe is made by rolling steel plate or strip into a tube, which is suitable for mass production and low cost requirements.
In addition, there are some special types of stainless steel pipes, such as ultra-low carbon 304 stainless steel pipes, nickel-based alloy steel pipes and so on. These special types of stainless steel tubes have higher strength, corrosion resistance and wear resistance, and are suitable for some areas with special requirements, such as the nuclear industry, aerospace and so on.
In summary, 304 stainless steel pipes can be classified according to factors such as wall thickness, production process and special needs to meet the needs of different industries and applications.
There may be many factors for the cause of porosity in stainless steel pipes. The following are some of the main reasons that may cause pores in stainless steel pipes:
Material issues: The use of low-quality stainless steel materials or materials that do not meet specifications can lead to the formation of pores. These materials may have defects, such as inclusions, bubbles or other unevenly distributed substances, which may lead to the formation of pores during processing.
Improper welding process: In the welding process, if the welding parameters are set incorrectly or improperly operated, such as too much current, too high voltage, too fast welding speed, etc., it may lead to overheating of the weld, resulting in porosity. In addition, the quality of the welding wire or protective gas may also have an impact on the formation of pores.
Improper heat treatment: In the heat treatment process, if the temperature is not properly controlled or the holding time is insufficient, it may lead to the internal organization of the stainless steel pipe is unstable and the porosity is generated. In addition, excessive cooling may also lead to the formation of pores.
Mechanical damage: During transportation, handling or installation, stainless steel pipes may be squeezed or hit by external forces, resulting in cracks or pores on the surface or inside. These mechanical injuries are usually related to the strength and toughness of the material.
Corrosion and contamination: Stainless steel pipes may come into contact with corrosive media or contaminants during use, which may erode the oxide layer on the surface of stainless steel, leading to the formation of pores. In addition, the cleanliness of the stainless steel surface will also have an impact on the generation of pores.
In summary, the reasons for the porosity of stainless steel pipes may be many, including material problems, welding process problems, heat treatment problems, mechanical damage, corrosion and pollution and other factors. To effectively avoid these problems, strict control and management are needed from the aspects of material selection, welding process, heat treatment, packaging and transportation.

Stainless steel is an alloy of iron and several other elements (such as nickel, chromium, molybdenum, and carbon) that is more resistant to corrosion than ordinary iron or steel (simple iron and carbon).
These stainless steel elements, such as nickel, chromium and other additives, give it a passivated oxide layer that prevents rust and forms a shiny reflective surface. Compared with ordinary steel, the glossy surface of stainless steel is difficult to tarnish, so it is called "stainless steel".
Ingredients
Stainless steel metal is nickel, iron ore, chromium, silicon, molybdenum and other raw materials fused together to form. Stainless steel metal contains a variety of basic chemical elements that, when fused together, form a powerful alloy.
Different proportions of stainless steel elements - iron, nickel, chromium, molybdenum, and carbon (among others) - determine the type of stainless steel. The ratio of iron to other materials affects the strength of the protective oxide layer, the resistance of the metal to specific corrodes, and some other mechanical properties (hardness, melting point, shear modulus, etc.).
These different proportions of stainless steel components produce different types of stainless steel alloys. Each unique combination is called a "grade" of stainless steel - for example, grade 304 stainless steel, grade 316 stainless steel or grade 420 stainless steel.
Definition of stainless steel: Iron based alloys containing more than 12% chromium are called stainless steel.
The most basic characteristic of stainless steel is its rust resistance under atmospheric conditions and corrosion resistance in various liquid media.
The meaning of stainless steel: Stainless steel is a general term for stainless steel and acid-resistant steel. Stainless steel refers to steel that is resistant to weak corrosive media such as atmosphere, steam and water, while acid-resistant steel refers to steel that is resistant to chemical etching media such as acid, alkali and salt.
There are great differences in alloying degree between stainless steel and acid-resistant steel. Although stainless steel is stainless, it is not necessarily acid resistant; Acid-resistant steels generally have stainless properties.
In the air or chemical corrosive medium can resist corrosion of a kind of high alloy steel, stainless steel is a beautiful surface and good corrosion resistance, do not have to go through plating and other surface treatment, and play the inherent surface properties of stainless steel, used in many aspects of steel, usually called stainless steel.
From the metallographic point of view, because stainless steel contains chromium and the surface of the formation of a very thin chromium film, this film is separated from the oxygen intrusion in the steel has a role in corrosion resistance. In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 12% chromium.
430 is a ferritic stainless steel, 430 16Cr as a representative of ferritic steel, thermal expansion rate, formability and oxidation resistance. Heat resistant appliances, burners, household appliances, Class 2 tableware, kitchen sink, external decorative materials, bolts, nuts, CD rods, screens.
304 is austenitic stainless steel, 304 18Cr-8Ni as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot processing good, no heat treatment hardening phenomenon (non-magnetic, use temperature -196℃~800℃). Household goods (Class 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molding products), medical equipment, building materials, chemicals, food industry, agriculture, Marine parts.
When the steel or sample is stretched, when the stress exceeds the elastic limit, even if the stress is no longer increased, and the steel or sample continues to have obvious plastic deformation, this phenomenon is called yield, and the minimum stress value when the yield phenomenon is generated is the yield point. With the development of building seismic technology and the in-depth analysis of seismic mechanism, energy dissipation seismic technology has become a developing trend of building seismic technology.
Performance requirement
In addition to the high strength and good plasticity of structural seismic steel, the strain-aging sensitivity, brittle transition temperature, low cycle fatigue resistance and welding properties of steel should also be considered. Low yield point steel is mainly used to make energy dissipation dampers, and its anti-seismic mode determines the performance requirements of steel.
In the earthquake, the energy dissipation damper is required to bear the seismic load before other structural parts, and repeatedly deforms in the plastic zone to absorb seismic energy, so as to achieve the purpose of earthquake resistance. Therefore, the low yield point steel must have a very low yield point and the yield range is controlled in a very narrow range, but also have good processing and welding properties, and have good plasticity, so as to have good deformation ability.
In addition, seismic steel is subjected to repeated alternating loads during an earthquake. The duration of strong earthquakes is generally within 1min, the amplitude frequency is usually 1~3Hz, and the damage of buildings is caused within 100~200 cycles, which belongs to high strain and low cycle fatigue. Therefore, the low yield point steel must have good resistance to low cycle fatigue.
