400 series stainless steel features and uses

400 series stainless steel

Stainless steel refers to alloy steel with corrosion resistance. The addition of chromium to the steel can form a dense oxide layer on the surface of the steel, which can prevent oxygen from further reacting with the steel, thus playing a role in corrosion resistance. The 400 series stainless steel is the most commonly used series of stainless steel.

peculiarity

1. Ferritic structure: Most of the 400 series stainless steel is ferritic, which has good toughness and is suitable for use in low temperature environment.

2. High chromium content: The chromium content of 400 series stainless steel is up to more than 12%, and this high chromium alloy has good corrosion resistance and wear resistance.

3.Universal machinability: 400 series stainless steel can be processed by cold processing, hot processing and forming processing.

4. Low cost: The cost of 400 series stainless steel is low, suitable for the production of some low-end products.

5. Magnetic: Most of the 400 series stainless steel is magnetic.

Use

400 series stainless steel has a wide range of applications in many fields:

1. Construction Industry

The 400 series stainless steel is suitable for the manufacture of finished products in the construction industry, such as doors, Windows, stair railings, bathroom equipment, etc. Because of the presence of chromium, 400 series stainless steel can still maintain long-term beauty and durability in the harsh environment of the city. At the same time, 400 series stainless steel has good fire performance, and can also be used for the manufacture of fire doors and fire Windows.

2. Manufacturing

400 series stainless steel is also widely used in the manufacturing industry, such as automobile manufacturing, shipbuilding, machinery manufacturing and so on. Exhaust pipes and carburetor parts in automobile production, ship components and desalination equipment in ships, as well as bearings and springs in machinery manufacturing are typical examples of the use of 400 series stainless steel. Because 400 series stainless steel has good corrosion resistance in salty environments, it is also widely used in Marine equipment manufacturing.

3. Chemical industry

Chemical pipes and containers generally need good corrosion resistance materials, and 400 series stainless steel will also be used at this time. For example, in the manufacture of chemical fertilizers, it is necessary to use calcium chloride with high chlorine content, the use of ordinary steel is easy to rust oxidation, but the use of 400 series stainless steel can ensure the stability and durability of the container.

4. Food industry

The material of food processing equipment must meet health standards, 400 series stainless steel because it does not contain harmful substances and corrosion resistance, is often used to make food processing equipment such as slicer, mixer, dryer and other equipment.

5. Home appliance manufacturing

The good properties of 400 series stainless steel also make it an important material for home appliance manufacturing. For example, for the refrigerator door panel and motor balance wheel, microwave oven furnace chamber, etc., the use of 400 series stainless steel can ensure the beauty of the product, long-term service life and corrosion protection.
