JFE Steel Corporation has begun producing its recently developed “GI JAZ” high-lubricity hot-dip galvanised (GI) steel sheet, which it claims offers dramatically improved press ‘formability’ for use in automobile bodies.
GI steel sheet, which is hot-dip galvanised to coat its surface of steel substrate with pure zinc for strong corrosion resistance, is used mainly by European and American automobile manufacturers.
GI JAZ incorporates the high-lubricity technology used in “JAZ” (JFE Advanced Zinc) on GA steel sheet, which is heated after galvanising to alloy the galvanised layer with iron of steel substrate to improve both its ability to be spot-welded and its corrosion resistance after painting.
