Abstract
The loss of zinc by vaporization when heating a zinc-aluminum coating to a temperature between about 427.degree. C. and 816.degree. C. (800.degree. F. and 1500.degree. F.) is significantly reduced by applying a zinc-aluminum coating containing about 30 to 75 weight percent zinc and the balance essentially aluminum to a mild carbon steel base which contains titanium in an amount sufficient to combine with all of the carbon in the steel and provide a small excess of uncombined titanium in the steel base, thereby providing a zinc-aluminum coated steel article which has improved corrosion and oxidation resistance when heated at temperatures between about 427.degree. C. and 816.degree. C. (800.degree. F. and 1500.degree. F.).
