Carbon steel forgings, manufactured in accordance with ASTM A105, are generally used for piping applications. These forged carbon steel piping components (including flanges, fittings, and valves, etc) are used for ambient- and higher-temperature service in pressure systems. The A105N, which is designated with a suffix “N”, denotes that the A105 forging shall be furnished in normalized condition. If the forgings …

ASTM A105/ A105M, identical with ASME SA-105/ SA-105M, is the standard specification for carbon steel forgings for piping applications. The application of ASME SA-105 forgings is endorsed by a series of ASME Boiler and Pressure Vessel Codes and ASME B31 Codes. However, the misuse of this material is commonly seen in some engineering practices. A typical misuse is that some …

The Part D of ASME Boiler and Pressure Vessel Code Section II has specified both tensile strengths and yield strengths for all 4 grades of ASTM A266/ ASME SA-266 forgings at elevated temperatures. The tabulated values in the following tables are provided for design calculation purpose. Tensile strengths at elevated temperatures *Table A-1: tensile strength value TS1, ksi, for ASTM …
