A-747 Steel Castings, Stainless, Precipitation Hardening

Description

This specification covers iron-chromium-nickel-copper corrosion resistance steel castings capable of being strengthened by precipitation hardening heat treatment. The steel shall be made by electric furnace process with or without separate refining such as argon-oxygen decarburization. The steel materials shall also undergo homogenization heat treatment, solution annealing heat treatment, precipitation hardening and shall conform to the required values of temperature and time and cooling treatment. The materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, columbium, and nitrogen.
