Abstract

SCC of 304 stainless steel(ss) in boiling MgCl2 at 416K was performed to investigated the effect of hydrogen during test. Results showed that the existence of hydrogen enhanced the susceptibility of SCC of 304ss. The fractography of specimen charged with hydrogen contained more intergranular than that of uncharged ones, and for the both specimens charged or uncharged with hydrogen, SCC initiated and propagated along { 111 } plane.
