The evaluation of normal anisotropy has been made by tensile test on TIRA test 2300 according standards STN EN 10002-1+AC1 and STN 42 0321. The evaluation of earring degree has been carried out on the cups, which have been drawn on a hydraulic press Fritz Muller 100 %K multiphase steels %K heat treatment %K coefficient of normal anisotropy %K degree of earing %K earring %K zinc coating %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=180645
