Precision Alloy Steel Valve Castings for High Heat

C5 (ASTM A217 C5), as a typical 9Cr-1Mo alloy cast steel, its outstanding high-temperature performance stems from the precise alloy ratio and is specially designed for extreme high-temperature working conditions up to 649 ° C (1200 ° F). In terms of composition, the core advantage lies in its high chromium content of 8.0-10.0%, which can quickly form a dense and stable Cr₂O₃ oxide film on the material surface. Even in a long-term high-temperature environment, it can effectively prevent the erosion of oxygen and corrosive media, significantly reduce the oxidation rate, and ensure that the material maintains structural integrity in a strong thermal corrosive environment. Molybdenum content of 0.9% to 1.1% significantly enhances the high-temperature strength and creep resistance of the material through solid solution strengthening. Under the working condition of 600℃, its creep fracture strength is more than five times that of ordinary carbon steel, and it can withstand high-temperature…
