　　ASTM A758/A758M-2014

　　中文名称：具有经改进冲击韧性的锻制碳素钢对接焊管道配件规格

　　英文名称：Standard Specification for Wrought-Carbon Steel Butt-Welding Piping Fittings with Improved Notch Toughness

　　原文名称：Standard Specification for Wrought-Carbon Steel Butt-Welding Piping Fittings with Improved Notch Toughness

　　范 围：This guide covers standard specification for wrought-carbon steel butt-welding seamless or welded fittings specially processed to ensure better notch toughness. Heat treatment shall be required for all types of fittings. Fittings with mandatory radiographic examination of welds shall be included. Cast fittings and fittings formed from all weld metal, shall not be included. Heat or cast analysis shall be conducted wherein the material shall conform to the required chemical components for carbon, manganese, phosphorus, sulfur, silicon, vanadium, chromium, nickel, molybdenum, copper, and lead. The fittings, as represented by tensile test specimens taken subsequent to final heat treatment, shall conform to the specified values of tensile strength, yield strength, and elongation for the applicable grades of steel. Mechanical tests such as tension test and transverse guided weld bend test shall be performed on the fittings.
