Popis:	The slow-strain-rate tensile test was used to investigate the susceptibility of 410 stainless steel to stress corrosion cracking (SCC) in (NH 4 ) 2 SO 4 solutions at ambient temperature. The effects of changing the pH, the concentration of the salt and the applied potential were studied. Under free corrosion conditions the quenched and tempered alloy was found to undergo SCC at pH values in the range 3–8.5. Failure at pH values below 3 was due to metal thinning, while at pH values above 8.5 ductile fracture occurred. The SCC was intergranular except at relatively high salt concentrations, in acid solutions and when the alloy was cathodically polarized in which cases mixed transgranular and intergranular cracks were observed.
