Abstract The effect of deformation-induced martensite (ferrimagnetic phase) on stress corrosion cracking of 1Crl8Ni9Ti stainless steel was investigated. Low temperature (-70℃) elongation method was used to obtain specimens with various martensite contents. SSRT was applied to investigate SCC susceptibility. Fracture morphology was observed with SEM. The results showed that when the content of ferrimagnetic phase was less than 5% or in the range of 16-25%, the SCC susceptibility of the material decresed with the increasing ferrimagnetic phase content. However, when the content of ferrimagnetic phase was in the range of 5-16% or more than 25%, its SCC susceptibility increased with the increasing ferrimagnetic phase content.
