The sensitivities of the stress corrosion cracking of types 304, 304L and 347 weldments were discussed with the specimens cutting from the base metals, heat affected zones and deposited metals of the weldments and tested in the boiling solution of 42 per-cents Mg Cl_2 under tensile loads. Under these conditions, the sensitivities of the stress corrosion cracking are affected with the yielding points rather than with the constructions and the compositions of the materials. Also, in the case of plastic working, the higher the order of deformation is, the lower the sensitivity of stress corrosion cracking is. Moreover, the stress corrosion tests of welded plates were carried out in the same corrosive solution as above. It become clear that the stress corrosion cracking occured by the residual stress is coincide with the results of the above tensile tests.
