A criterion for evaluating and predicting the sour resistance of high alloy is presented through multiple regression analysis of laboratory data with the aid of a computer. Sour Resistance is defined as a polarization resistance in anodic dissolution of metals which do not form passive films in sour environments. Sour Resistance value defined in this study, SR, consists of major alloy components and their coefficients which are the function of given environmental parameters.

SR value showed useful relationships with corrosion behaviors of high alloys tested in NACE solution and brine solutions under high partial pressure of H2S and CO2 at temperature up through 250°C.
