Explanation
Cobalt based high temperature alloy that is directly casting or directional solidification from qualified parent alloy after remelting to form parts or parts blanks, and about 10% nickel is added to the cobalt base to form stable γ Austenite matrix; Add 20% -30% chromium to form Cr2O3 oxide film with good protective performance on the surface of parts, and improve the performance of anti-oxidation and corrosion resistant parts; More W or a small amount of Mo is added for solution strengthening. More carbon (0.3% -0.8%) is added to form carbide for precipitation strengthening.
