Through the present investigation, the effect of temperature of torsional working on the torsional creep strength of 18-8 stainless steel has been obtained. The specimens were twisted to a degree of 0.128π/cm or 0.256π/cm at several temperatures from-60°C to 800°C beforehand, and then their torsional creep strengths for 450, 500 and 720°C were measured.
The torsional creep strength increases as the temperature of torsional working rises, and reach the maximum for the specimens worked at 300-600°C.
