Ambient Temperature Creep of Type 304 Stainless Steel

Abstract

This study reports the significant ambient temperature creep plasticity at stresses below the conventional 0.2% plastic strain off-set yield stress. This is partially due to the relatively high strain-rate sensitivity of 304 stainless steel. Cold-working significantly increases the creep resistance. Descriptive equations that predict low-stress creep plasticity, which are somewhat different than traditional creep-equation forms, are presented.
