　　中文名称：低温和中温一般腐蚀用焊接的锻制奥氏体不锈钢配件规格

　　英文名称：Standard Specification for As-Welded Wrought Austenitic Stainless Steel Fittings for General Corrosive Service at Low and Moderate Temperatures

　　原文名称：Standard Specification for As-Welded Wrought Austenitic Stainless Steel Fittings for General Corrosive Service at Low and Moderate Temperatures

　　范围：This specification covers five grades of as-welded, wrought austenitic stainless steel fittings for low-pressure piping and for low and moderate temperatures and general corrosive service. The fittings shall be made from flat-rolled steel which shall be in the solution annealed condition. The fittings shall be formed by a hot or cold process and shall be welded by a shielded welding process with or without the addition of filler metal. Heat analysis and product analysis shall be performed where in the steel fittings shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, titanium, columbium, tantalum, and nitrogen. The steel materials shall also undergo mechanical tests and shall conform to the required values of tensile strength, yield strength, elongation, and hardness.
