Part 3 of this European Standard, in a4dition to part 1, specifies requirements for flat products made of weldable, hot-rolled, high yield strength steels for cold forming. The grades are given in table 1 (chemical composition) and table 2 (mechanical properties) and are supplied in the normalized or normalized rolled delivery condition as given in 7.2. The steels specified in this European Standard are applicable to hot-rolled flat products in the thickness range of ü 1,5 mm and ¿ 20 mm.
