Allowable stress values for piping materials are provided in Table A-1 of ASME B31.3. This page provides a convenient and valuable tool for calculating allowable stress values of piping materials at intermediate temperatures.
To minimize the size of dropdown box, the tool is split by material type. The first section provides the allowable stress values for carbon steel materials including pipes, plates, forgings and castings. Allowable stress for other materials will be uploaded shortly.
Allowable Stress for Carbon Steel piping materials
Select the applicable piping material from the dropdown box below. Then input the temperature either in degrees Farenheit or degress Celsius for which you require the allowable stress values. The calculator compiles the interpolated stress values and presents these values in multiple units.
