Specification for Castings, Nickel and Nickel Alloy
ASTM A494 specification covers nickel, nickel-copper, nickel-copper-silicon, nickel-molybdenum, nickel-chromium, and nickel-molybdenum-chromium alloy castings for corrosion resistant service. ASTM A494 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.

All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Nickel-Copper alloys generally contain at least 50% nickel, and may contain significant amounts of chromium and molybdenum. These metals were developed to provide greater strength at high temperatures, and greater corrosion resistance (including high temperature corrosion) than could be obtained from iron and steel.
