CarTech Micro-Melt 440C alloy is a powder metallurgy, high-carbon chromium stainless steel designed to provide stainless properties with maximum hardness. When heat-treated, CarTech Micro-Melt 440C attains the highest hardness of any stainless steel (about HRC 61.5).

Applications:
CarTech Micro-Melt 440C alloy has found application in specialty knife blade applications. Its fine carbide distribution and fine-grained microstructure enhance cutting performance as much as 40% better than equivalent cast/wrought steels. Other uses for this stainless steel include bearing assemblies, including bearing balls and races. In addition, the material should be considered for needle valves, ball check valves, valve seats, pump parts, ball studs, bushings and wear-resistant textile components.
