Tempering & Hardness. For 440A and 440B stainless steel, 150 °C – 370 °C, and can get the HRC hardness 49-57 for 440A, 53-59 for 440B steel. For 440C stainless steel, tempering temperature and corresponding HRC hardness, as follows. Max 160 °C, ≥ 60 HRC. Max 190 °C, ≥ 58 HRC.
440 stainless steel is renowned for its impressive hardness. The steel’s hardness largely comes from its high carbon and chromium content. 440A, the least hard variant, typically measures between 56-58 on the Rockwell C scale (HRC). 440B is slightly harder, with an HRC of 58-60. 440C, with the highest carbon content, measures between 58-60 ...
Grade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment. These properties make this grade suitable for applications such as valve components and ball bearings.
The alloy 440 stainless steel is a hard, brittle, and weldable steel with a high carbon content in its chemical composition. It has widespread applications in many sectors, including healthcare and household appliances, due to its elevated level of hardness, resistance to wear and surface deformation, and strength.
CarTech 440C stainless is a high-carbon chromium steel designed to provide stainless properties with maximum hardness. It has been used primarily as a bearing steel, and is used in the hardened plus tempered condition.
Stainless 440C is a high-carbon martensitic stainless steel. As a martensitic stainless steel, 440C is magnetic and can be hardened by heat treatment. The high carbon content in 440C provides high hardness and strength.
440C should be annealed for maximum softness by thorough soaking at 1650°F for six hours followed by a furnace cool. This grade can be *cycle annealed by heating to 1600°F, holding two hours, cooling to 1300°F, and holding four hours. The steel may be cooled in air if desired.
Feb 20,2024 2565. Introducing to the world of 440C stainless steel, a material known for its remarkable properties along with wide range of applications. In this era, where strength, durability and performance are the dominant factors for any application, this alloy plays a key role in that aspect.
Once heat-treated, 440C achieves the highest hardness and wear resistance of any stainless steel currently available. It is particularly suited to applications such as valve parts and bearings. Alloy 440C is relatively easy to machine in the annealed condition.
Overview. High strength, moderate corrosion resistant, good hardness and wear resistant material. After heat treatment, Stainless 440C is capable of attaining the highest strength, hardness and wear resistance of all the stainless alloys.
