This European Standard, in addition to EN10149-1, specifies requirements for flat products made of weldable, hot-rolled, high yield strength steels for cold forming.
The grades are given in Table1 (chemical composition) and Table2 (mechanical properties) and are supplied in the thermomechanically 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:
1,5mm to 20mm for the steels which have a specified minimum yield strength of 315MPa 1) up to and including 460MPa1);
1,5mm to 16mm for the steels which have a specified minimum yield strength of 500MPa1) up to and including 700MPa1); and
from 2mm up to 10mm for the steels with a minimum yield stress in the range from 900MPa1) to 960MPa1).
