What is sus440c Heat resistant stainless steel

SUS440C is a heat-resistant stainless steel, belonging to martensitic stainless steel, with high hardness, high wear resistance and high corrosion resistance characteristics. It is composed of chromium, cobalt, molybdenum, manganese, silicon, vanadium and other elements, of which chromium content is the highest, up to 16-18%. SUS440C heat-resistant stainless steel performs well in high temperature, high pressure and high strength environments, and is widely used in automotive, aerospace, medical equipment, tools, molds and other fields.

What are the features?

After proper heat treatment, SUS440C heat-resistant stainless steel can reach a hardness of 60-62HRC, which is much higher than ordinary stainless steel. Therefore, it can be used to manufacture parts with high hardness, such as bearings, tools, etc.

The high hardness of SUS440C heat-resistant stainless steel makes it have excellent wear resistance and can maintain stable surface quality for a long time under high speed movement and heavy load. It can be used to manufacture bearings, gears and tools for high speed movement.

The high chromium content of SUS440C heat-resistant stainless steel makes it have good corrosion resistance and can be used for a long time in corrosive media such as acid, alkali and salt. It can be used to manufacture chemical equipment, Marine accessories and so on.

SUS440C heat-resistant stainless steel can still maintain good mechanical properties and corrosion resistance at high temperatures, and can be used for equipment manufacturing at high temperatures.

SUS440C heat resistant stainless steel applications

SUS440C heat-resistant stainless steel is widely used in the mold manufacturing industry because of its high hardness, high wear resistance and high corrosion resistance. Molds are key components in the manufacture of various industrial products, requiring high precision and long life. SUS440C heat-resistant stainless steel can be used to manufacture injection molds, extrusion molds, die casting molds, stamping molds, etc.

The high hardness and high wear resistance of SUS440C heat-resistant stainless steel make it an ideal material for the manufacture of high-grade tools. Cutting tools are the core parts of various processing equipment, which require excellent cutting performance and long service life. SUS440C heat-resistant stainless steel can be used to manufacture various types of cutting tools, such as saw blades, milling cutters, drills, planers, etc.

SUS440C heat-resistant stainless steel is widely used in the aerospace field. Aerospace equipment needs to have high strength, high hardness, high wear resistance and high corrosion resistance, and SUS440C heat-resistant stainless steel just has these characteristics. It can be used to manufacture parts for various aerospace equipment, such as aircraft engine impellers, thrusters, propellers, etc.

SUS440C heat-resistant stainless steel is widely used in the field of medical devices. Medical devices need to have high precision, high corrosion resistance and high hygiene characteristics, and SUS440C heat-resistant stainless steel can meet these requirements. It can be used to manufacture scalpels, needles, dental instruments, etc.
