Description
Alloy 440C
There are two types of stainless steel: 440C, which is high carbon straight chromium high hardenability martensitic stainless steel, and 440D, which is high carbon straight chromium high hardenability martensitic stainless steel, both of which can have a maximum Brinell hardness of 285 (Rc29) or 269 (Rc29) (Rc31). When it's hardened and tempered, it has a lot of strength, hardness, and wear resistance, but it's also very resistant to corrosion in mild domestic and industrial environments, like fresh water, organic materials, mild acids, and many petroleum products. Because of its good hardenability, 440C can be hardened all the way through to Rc60, depending on the carbon content and the size of the piece. Small parts can be air cooled and large parts can be oil quenched to get the best through hardness. for parts that need a lot of wear resistance and a lot of corrosion resistance at the same time.
