Inconel 722 nickel-based alloy is an alloy composed of nickel-based and other elements. It belongs to a kind of nickel-chromium alloy, nickel-iron alloy, nickel-copper alloy and nickel-molybdenum alloy. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve some physical properties. It has excellent corrosion resistance and oxidation resistance, and has good tensile properties and fatigue properties from low temperature to 980 ° C, and is resistant to stress corrosion in salt spray atmosphere.
