440C Stainless Steel Coil Description

440C grade stainless steel is a kind of high carbon martensitic stainless steel. High strength, medium corrosion resistance, good hardness and wear resistance. Grade 440C achieves the highest strength, hardness and wear resistance of any stainless steel alloy after heat treatment. Its extremely high carbon content is the reason for these characteristics, which makes the 440C particularly suitable for applications such as ball bearings and valve parts.
