WebThey are a combination of martensitic and austenitic steels. Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the ... WebHardness is developed by a solution heat treatment followed by an aging treatment, through which a second, hardening phase is formed. Hardness for 17-4 PH ranges from Rc 29 to Rc 44. These types have higher corrosion resistance than the martensitic varieties and offer higher bulk hardness than do 200- and 300-series materials. cst borotra
