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
26、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 MPa1)up to and including 460 MPa1); 1,5 mm to 16 mm for the steels which have a specified m
27、inimum 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). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indi
