1) Remark: ZStE 420, material number 1.0556 according to SEW 093 (steel-iron material specifications) is a microalloyed higher-strength steel with a minimum yield strength of 420 N/mm² and a minimum ultimate strain of 16%. The material can be cold-formed well and is used as carrier material for: - hot-dip refined strips and sheets - electrolytically refined strips and sheets: Thin sheets made from higher-strength formable steel allow in certain areas of use a decreased sheet thickness (and thus decreased weight of the construction component) without impairing the strength of the construction component. Areas of use are the automobile industry, plant construction, building and others. The material is used as carrier material for: - electrolytically refined strips and sheets: manufacturer/product: Krupp/Hoesch: Zincal, Momozincal Thyssen: ZStE 420 ZE Voest-Alpine: Gravigal Zn, ZnNi BREGAL-Bremen: ZStE 420 ZE, ZNE Otto Wolf: ZStE 420 ZNE - hot-dip refined strips and sheets: manufacturer/product: Krupp/Hoesch:Galvatect, Galfan, Galvalume Thyssen: Galvanealed, Monogal Voest-Alpine: Thervagal Zn, ZnFe, ZnAl BREGAL-Bremen: Galvanealed, Galfan EKO Stahl AG: strip, hot-dip galvanized
