Notes:
In this study, the creep rupture tests of STS304 stainless steels were investigated at threedifferent elevated temperatures of 600[removed info], 650[removed info] and 700[removed info] under the constant creep stresses.Creep rupture characteristics such as creep stress, creep rupture time, steady state creep rate and soon were evaluated. The behaviors of creep rate curve and initial strain are compared at threedifferent elevated temperatures. The stress exponent (n) at 600[removed info], 650[removed info] and 700[removed info] based onsteady state creep rate showed 22.5, 20.6 and 11.4 respectively. By increasing the temperature, thestress exponent is decreased. At the temperature of 700[removed info], the lowest stress exponents are shownand this behavior is also observed in the case of stress exponent based on rupture time. The creeplife prediction by LMP method is presented and the equation of this result is as follows:T(logtr+20)=-0.00515[removed info]2-14.56[removed info]+24126
