Summary
Tensile properties of commercial heats of modified 9 Cr-1 Mo alloy are presented for test temperatures in the range from room temperature to 760/sup 0/C. Data included the effects of melting practice, compositional differences, strain rate (8.0 to 0.00008/min), postweld heat treatment (1 through 112 h at 732/sup 0/C), tempering temperature (732 and 746/sup 0/C versus 760/sup 0/C), isothermal annealing (1038/sup 0/C for 1 h and 704/sup 0/C for 24 h followed by AC), and thermal aging (5000 and 11,600 h at 538, 593, and 649/sup 0/C). The average-to-minimum property range for the yield and ultimate tensile strengths was compared with the similar data range for standard 9 Cr-1 Mo alloy. Tensile data on commercial heats were used to set the room-temperature specified minimum values for the alloy. The conservativeness of the specified minimum values was checked against the data at several strain rates, data after postweld heat treatment at 732/sup 0/C up to 112 h, and data on thermally aged material.
