    Abstract

    In 1962 C. P. Larrabee and S. K. Coburn published an extensive collection of atmospheric exposure data showing the effect of variations in copper, nickel, chromium, silicon, and phosphorus content on the corrosion resistance of low-alloy steel. Two hundred and seventy steel alloys of different composition were exposed for 15½ years at three separate locations representing industrial, semirural, and marine atmospheres. Among these experimental steel compositions there were five levels of copper concentration, two levels of nickel concentration, three levels of chromium concentration, three levels of silicon concentration, and three levels of phosphorus concentration represented. A statistical analysis of these data has been conducted and the results of the analysis are presented and discussed.
