ASTM A403 Standard specification covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. ASTM A403 / A403M Standard Specification for Wrought Austenitic Stainless Steel Piping Fittings.The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations.
All fittings shall undergo heat-treatment. Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, and titanium. Fittings supplied under this specification shall be examined visually for surface discontinuities, surface checks, and mechanical marks.
