Abstract
The stress corrosion cracking (SCC) susceptibility of type 316 stainless steel in 3.4 per cent NaCl with different concentrations of thiosulphate solution and the inhibiting effect of benzotriazole (BTAH) on SCC were investigated by slow strain rate technique. The addition of BTAH to test solution produces an inhibitive effect on the stress corrosion susceptibility (S). The mode of cracking changed from brittle transgranular to ductile failure at higher concentrations of BTAH. Some electrochemical measurements were obtained to complement the SCC measurements. The results indicated that the inhibitive action of BTAH can be attributed to its adsorption and inhibiting the anodic dissolution of the alloy by the effect of blocking the active sites on the alloy surface.
