CEN PREN 10149-2: Hot rolled flat products made of high yield strength steels for cold forming - Part 2: Delivery conditions for thermomechanically rolled steels

Publication Date: Mar 1, 2011
SDO: CEN: European Committee for Standardization
 DOD Adopted   ANSI Approved Approved

Part 2 of this European Standard, in addition 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 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 MPa1) 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

— 2 mm to 8 mm for the steels which have specified minimum yield strength of 900 MPa1) up to and including 960 MPa1).

1) 1MPa = 1N/mm2.
