A-494 Castings, Nickel and Nickel Alloy

Description

This specification covers nickel, nickel-copper, nickel-copper-silicon, nickel-molybdenum, nickel-chromium, and nickel-molybdenum-chromium alloy castings for corrosion resistant service. The castings shall be heat treated. When Class 1 is specified, grades CY40 and M25S shall be supplied in the as-cast condition. When Class 2 is specified, grades CY40 and M25S shall be supplied in the solution treated condition. When Class 3 is specified, grade M25S shall be supplied in the age-hardened condition. The chemical composition requirements of the alloys are presented. The tensile property requirements including the heat treatment procedure for the castings are presented in detail. It is required that one tension test shall be made from each master heat except for grades M25S and CY5SnBiM when the master heat is used to pour the castings. One tension test shall be made from each melt except for grades M25S and CY5SnBiM. Test results shall conform to the specified tensile requirements.
