Stellite 706 is a cobalt-based alloy containing chromium, molybdenum, and carbon, designed for components exposed to combined wear and corrosion. Its nominal composition includes 31% chromium, 4% molybdenum, and 1.2% carbon by mass, with cobalt as the balance and a typical hardness of 39–43 HRC. It offers a balance of wear resistance and ductility within the 700 series, making it a candidate for valve seats, sliding components, and flow-control parts operating in corrosive environments.
