The SCC susceptibility of 1Cr18Ni9Ti austenitic stainless steel in 0.5 mol.L-1 HCl+0.5mol.L-1 NaCl solutions and the inhibiting effect of benzotriazole (BTA) for SCC and general corrosion were investigated by slow strain rate technique (SSRT), polarization measurements and electrochemical impedance spectroscopy. The results indicated that the inhibitive action of BTA can be attributed to its adsorption and inhibiting effects on the anodic reaction of metal dissolution due to the blocking of the active sites on metal surface.
