It is verified that stainless steel AISI 321 is in the active anodic dissolution state in 0.5 mol/L HCll+0.5 mol/L NaCl solution at 55℃.The SCC of the steel in the solution can not be reasonably explained by passive film rupture-nepasivation theory and by hydrogen embrittlement theory.There are evidences that the fracture stress at the tip of the cracks is reduced by anodic dissolution due to its role in relieving strain hardening layer at crack tip.
