What is the yield strength of 440c stainless steel?

440C stainless steel is a high carbon stainless steel, belonging to the 440 series of stainless steels. Compared with 440A and 440B, it has higher hardness, wear resistance and corrosion resistance.

The main characteristics of 440C stainless steel are high hardness, excellent cutting performance, good corrosion resistance and strong wear resistance. It contains 17% chromium, 0.95% carbon and 1.2% molybdenum, and is a high alloy stainless steel. Due to its excellent hardness and cutting performance, it can be used to manufacture high-quality knives, hand tools, clubs, pulleys, bearings and other mechanical parts. At the same time, due to the presence of molybdenum, its corrosion resistance is also stronger than 440A and 440B.

Mechanical properties of 440C stainless steel
Density: 7.75 g/cm³
Hardness (Rockwell hardness): 58-62 HRC
Tensile strength: ≥2000 MPa
Yield strength: ≥1900 MPa
Elongation: ≥2%
Melting point: 1427-1515℃

However, since 440C stainless steel contains high carbon and chromium elements, the following points should also be noted during use:
Avoid long-term exposure to environments containing chloride ions, especially under high temperature and high humidity.
Avoid contact with other metal materials to prevent electrical corrosion.
When manufacturing mechanical parts such as cutting tools, care should be taken to ensure the hardness and cutting performance of 440C stainless steel to avoid excessive heat and mechanical stress during processing.
