Learn about the chemical composition, physical and mechanical properties, heat resistance and heat treatment of AISI SS 440 stainless steel grades 440C, 440A and 440B. See datasheet, specification, equivalent chart and hardness for each grade.
440C stainless steel is a high-carbon martensitic stainless steel, high carbon content in 440C provides high strength, moderate corrosion resistance, good hardness, and wear resistance. these characteristics make 440C particularly suited to such applications as ball bearings and valve parts, it has the highest hardness among stainless steel.
Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make 440C particularly suited to such applications as ball bearings and valve parts.
