ABSTRACT:
Continuously hot dip aluminum coated ferritic chromium alloy steel strip. After the steel has been given a pretreatment to remove surface contaminants, the steel is protected in a hydrogen atmosphere until it is passed into the molten aluminum coating metal. The coating metal readily wets the steel surface to prevent uncoated areas or pin holes in the coating layer.
