Susceptibility of stress corrosion cracking (SCC) of duplex stainless steel, SUS329J1 was investigated in 42%MgCl₂.aq. sol. (416 K). Results were as follows:<BR>Effect of structural anisotropy for SCC were studied. It was made clear that SCC was more susceptible in the case of crack growth being parallel to main rolling direction than in other cases and crack tend to propagate along α phase other than γ phase. In addition, SCC susceptibility was remarkably high in welded plates, although 329J1 base metal had high resistance to SCC. This would be caused that the residual stress were higher for its high yielding strength of base metal.
