This European Standard, in addition to EN 10149-1, 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 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: - 1,5 mm to 20 mm for the steels which have a specified minimum yield strength of 315 MPa ) up to and including 460 MPa1); - 1,5 mm to 16 mm for the steels which have a specified minimum yield strength of 500 MPa1) up to and including 700 MPa1); and - from 2 mm up to 10 mm for the steels with a minimum yield stress in the range from 900 MPa1) to 960 MPa1).
