Abstract
Stress corrosion cracking (SCC) and passivation behaviour of ultra‐high strength steel 23Co14Ni12Cr3 in neutral 3.5 wt% NaCl solution were investigated by slow strain rate test, surface analysis techniques and electrochemical measurements. The passive film on the steel is mainly composed of Fe, Co, Cr and Ni oxides and hydroxides. At potentials less than −850 mVSCE, SCC is controlled by hydrogen induced cracking (HIC). The passive film decreases SCC susceptibility of the steel at −400 mVSCE. While, HIC plays a dominant role on SCC mechanism at OCP.
