The tensile strengths and yield strengths of ASTM A105/ ASME SA-105 forgings at elevated temperatures are provided in ASME Boiler and Pressure Vessel Code Section II Part D. These values, which are tabulated in below two tables, are provided for use in design calculations. Neither ASME Codes nor ASME material specifications require elevated temperature testing for tensile strengths and yield strengths of ASTM A105/ ASME SA-105 forgings for use in Code components.
