Abstract

A method of fluxless hot dip metallic coating of low alloy steel strip and sheet containing aluminum, titanium, silicon, chromium, and/or mixtures thereof. A surface readily wettable by molten coating metal is obtained by heating the steel to a temperature of about 1100 DEG to 1675 DEG F in an atmosphere oxidizing to iron, then further treating under conditions which will reduce the iron oxide, whereby to form a surface layer comprising a substantially pure iron matrix containing a uniformly distributed fine dispersion of oxides of the alloying elements.
