Stainless steels: 304, 316, 17-4PH and 430 were selected to study their relative susceptibility to hydrogen embrittlement and alkaline corrosion under battery environments. Polarization results indicate that the corrosion rate increased significantly after welding. Austenitic steels showed a lower corrosion rate than the others. The stress corrosion cracking susceptibility has also been determined on U-bend specimens by immersion tests and using slow strain rate tensile testing with cathodic H2 charging. The results show that 17-4PH suffered severe corrosion after long immersion in electrolyte. The austenitic steels were found to be suitable materials for a Ni/MHx battery container.
