Resistance of Titanium-Base Alloys to Atmospheric Corrosion

Eight titanium alloys were included in the 1957 ASTM Committee G-1 (formerly B-3) program to determine the atmospheric corrosion behavior of nonferrous metals and alloys. Representative alloys of the alpha, alpha-beta, and beta type were evaluated. Based upon results of weight change measurements and tension tests, two- and seven-year exposures at four prominent ASTM test sites resulted in no significant corrosion. Slight staining was observed, but there was no appreciable weight change.
