Stellite 712

Stellite 712 is a cobalt-based chromium-molybdenum alloy designed for applications requiring wear and corrosion resistance at elevated temperatures. Its nominal composition includes 31% chromium, 8% molybdenum, and 1.6% carbon by mass, with cobalt as the balance and a typical hardness of 47–51 HRC. Its higher carbon and molybdenum contents distinguish it from Stellite 706, supporting a harder material for demanding wear conditions. Potential applications include valve seats, slides, and refinery flow-control components exposed to simultaneous mechanical wear and chemical attack.
