摘要

The stress corrosion cracking (SCC) of a commercial austenitic stainless steel type 316 was investigated as a function of sensitizing temperature (750-1300 K) and test temperature (333- 373 K) in 0.82 kmol/m~3 hydrochloric acid (HCl) solution by using a constant load method. From the applied stress dependence of three parameters (i_ss: steady state elongation rate, t_ss: Time interval of SCC-dominated failure, t_f: time to failure), the relationships between applied Stress and the three parameters were divided into three regions that are dominated by either Stress, SCC or corrosion.
