Compressive strength and creep of 17-7 PH stainless-steel plates at elevated temperatures

Bland A. Stein
Jul 1958

Compressive strength test results from room temperature to 1,000 degrees F and compressive creep test results from 700 to 1,000 degrees F are presented for plates of 17-7 PH stainless steel, Condition TH 1,050, which were edge-supported in V-groove fixtures. Plate width-thickness ratios range from 15 to 60. The combinations of average stress, temperature, and time that produce given amounts of creep strain or failure are shown on master curves which facilitate interpolation of the test results. The test results are compared with plate strengths and creep failure stresses determined from semiempirical approximations.
