Advanced Heat-Resistant Alloy Valve Castings

WC6 (ASTM A217 WC6), as a classic model of 1¼Cr - ½Mo alloy cast steel, its outstanding high-temperature performance stems from the precise alloy ratio and is specially tailored for high-temperature and high-pressure working conditions up to 593 ° C (1100 ° F). In terms of composition, 1.0-1.5% chromium is the core guarantee for resisting high-temperature oxidation. It can quickly form a dense and stable Cr₂O₃ oxide film on the material surface. Even when exposed to high-temperature environments for a long time, it can effectively prevent the erosion of oxygen and corrosive media, significantly reduce the oxidation rate, and ensure that the material maintains structural integrity when the thermal load fluctuates. The molybdenum content of 0.44-0.65% significantly enhances the high-temperature strength and creep resistance of the material through solid solution strengthening. Under the working condition of 550℃, its creep fracture strength far exceeds that of ordinary carbon steel, and…
