Abstract
Steel product in coil form such as sheet steel is uncoiled, then preheated, continuously transported through a lead bath containing chromium, then cooled, and finally recoiled. When the coiled steel does not have titanium, titanium is included in the bath in order to improve the corrosion resistance of the final product.
