Abstract A series of mixed mode tests were carried out on 18-8 stainless steel in boiling 42％ MgCl_2 solution. The results show that for any K_(II)/K_I ratio, the SCC direction coincides well with the crack tip maximum normal stress plane, while the SCC resistance of the material reduces as the ratio of K_(II)/K_I increases. The experimental results were discussed in the light of anode dissolving mechanism and the effect of mixed mode loading on crack tip stress and strain. It is concluded that for fracture analysis if mixed mode cracks were simply taken into account as mode I cracks, and only mode Ⅰ testing results as well as mode Ⅰ fracture criterion were employed, it may not be safe.

Key words: 18-8 stainless steel stress corrosion mixed mode
