This investigation was conducted to determine mechanical properties of several high performance alloys at room and elevated temperatures. The effects of temperature up to 1900 F and exposure up to 1000 hours at temperature on the tensile, compressive, bearing and shear properties were determined from measured stressstrain information in both the elastic and plastic range. The following materials were considered 301 extra hard stainless steel Ph157MoTH 1050 AM 355 Rene 41 and N-155. All material was from 0.050-inch sheet, except the material for the 18-inch diameter shear pins, which were fabricated from 14-inch plate. Heat treatment was in accordance with existing specifications for the materials, or other procedures approved by ASD to develop the optimum strength properties. Descriptions of the test specimens, equipment, and procedures are included. Test results are reported in tables and in curves showing the effects of temperature and time on the various mechanical properties.
