440C stainless steel is a high carbon type of stainless, this is the alloy most often used for knife-making. Can be heat treated for high strength and hardness. 440C stainless steel has greater abrasion and wear resistance for use in bearing and bushing applications. Corrosion resistant only in the hardened condition.
Grade 440C ss is a high carbon martensitic stainless with moderate corrosion resistance good strength, and the ability to obtain and hold excellent hardness (Rc 60) and wear resistance. 440C stainless steel is considered to be slightly cold workable by common practices and does respond to heat treatment.
