　　ASTM A758/A758M-2014

　　中文名稱：具有經(jīng)改進沖擊韌性的鍛制碳素鋼對接焊管道配件規(guī)格

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

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

　　范 圍：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.
