Abstract

In this work, hydrogen effects on passivation and stress corrosion cracking (SCC) of 2205 duplex stainless steel (DSS) in acidified seawater were investigated. Results show hydrogen deteriorates passive film, accelerates localized anodic dissolution (AD) and causes hydrogen damage, leading to high SCC susceptibility by hydrogen embrittlement (HE) and hydrogen facilitated anodic dissolution (HFAD). SCC initiates in ferrite, and propagates as transgranular-SCC (TGSCC) and intergranular-SCC (IGSCC). When loaded along rolling direction (RD), hydrogen segregating in austenite hardens austenite during SCC propagation; while hydrogen enriching in ferrite causes hydrogen enhanced localized plasticity (HELP) effect for transverse direction (TD) load.
