This specification covers austenitic-ferritic (duplex) stainless steel castings for valves, flanges, fittings, and other pressure-containing parts. The grades of steels covered here are: Grade 1B, Grade 2A, Grade 3A, Grade 4A, Grade 5A, and Grade 6A. The steel castings shall be heat-treated up to required temperature and shall undergo water quenching or rapid cooling by other means after heating. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, copper, tungsten, and nitrogen. All steels shall undergo tension test, and shall conform to the following mechanical requirements: tensile strength, yield strength, and elongation.
