Abstract:  
The effects of the shot-peening on the stress corrosion cracking (SCC) of martensitic and austenitic stainless steels were investigated. It was concluded that higher dislocation density and the compressive residual stresses in the surface layer are two important factors which can improve the resistance to SCC for stainless steels, and the cleavage-like fracture of austenitic stainless steel in the case of SCC exhibits, in fact, a cleavage-like fracture of plastic induced martensite.
