Abstract

A kind of strain hardening austenitic stainless steel widely used in cryogenic pressure vessels was adopted. A series of systematic experiments were performed and the results were presented concerning the monotonic tension and fatigue mechanics properties of stainless steel at room and liquid nitrogen temperature (-196°C). The fatigue life of low cycle, and high cycle, and the monotonic stress-strain curve were tested and discussed. The results were compared and found obviously different at room temperature and ultra-low temperature. The strength and fatigue life of the stainless steel were improved, while the ductility and plasticity decreased visibly at ultra-low temperature. The curve of the maximum stress Smax versus the cycle number to failure Nf at -196°C was obtained and contributed to safety design of the cryogenic vessels.
