JFE Steel developed JAZ~®, a new GA with an excellent lubrication property, using an original surface modification technique. JAZ~® has excellent press formability in actual press forming. JAZ~® also has other quality properties (spot weldability, adhesion property, phos-phatability, corrosion resistance) equal to those of conventional GA. Among its features, JAZ~® is an environment-friendly product because it contains no heavy metals or other harmful substances. Possible applications include side panels, fenders, doors, wheel houses, and other hard-to-form exposed panels and inner panels of automobile bodies. JFE Steel has positioned JAZ~® as a strategic product in high lubrication GA steel sheets for automotive applications. Mass production systems have been established at both East Japan Works (Chiba District) and West Japan Works (Fukuyama District), and full-scale supply to multiple auto makers has begun. The company has also completed installation of equipment at the hot dip galvanizing line (CGL) at Guangzhou JFE Steel Sheet (China) and at No. 4 CGL at West Japan Works (Fuku-yama) and plans to expand supply in the future.
