This publication describes the development of isochronous stress-strain curves and external pressure charts in the creep regime for 9Cr-1Mo-V steel for temperature ranges of 800°F to 1200°F and the time range of up to 300,000 hours. This publication reviews the generation of creep model equations for 9Cr-1Mo-V steel, the conversion of physical data and stress-strain creep model equations into isochronous curves, development of equations for construction of external pressure curves and carts for 9Cr-1Mo-V steel, and the derivation of equations for designing components in the creep regime.
