AISI 400C is a high carbon chromium steel is designed to provide stainless steel properties with maximum hardness.
After heat-treatment Type 440C attains the highest hardness of any stainless steel (about 60 HRC).
This stainless steel is principally used for bearing assemblies including ball bearings and should be considered for needle valves and ball check valves.
