Pyrowear® 675 is a carburizing, corrosion-resistant steel designed to provide a case hardness in excess of HRC 60 combined with a tough, ductile core. The corrosion resistance of carburized Pyrowear 675 is similar to that of 440C stainless, while the core toughness is similar to that of AISI 9310. In addition, the alloy provides excellent hot hardness capability. Pyrowear® 675 has been used in bearing and gearing type applications. The alloy should also be considered for any application requiring parts with a hard, corrosion-resistant case and a tough, ductile core.
