Specification for hot-rolled flat products made of high yield strength steels for cold forming. General delivery conditions (British Standard)
1.1 This European Standard specifies requirements for flat products made of weldable, hot-rolled, hith yield strength alloy quality and special steels for cold forming. Part 1 of this European Standard specifies the general delivery conditions. Part 2 of this European Standard specifies the delivery conditions for thermomechanically rolled steels in the grades given in table I (chemical composition) and table 2 (mechanical properties) of Part 2. Part 3 of this European Standard specifies the delivery conditions for normalized or normalized rolled steels in the grades given in table 1 (chemical composition) and table 2 (mechanical properties) of Part 3. The steels specified in Part 2 and 3 of this European Standard are applicable to hot-rolled flat products in the thickness range of 1,5 mm to 20 mm for the steels with Reh ¿ 460 N/mm2 and 1,5 mm to 16 mm for the steels with higher minimum yield strength. 1.2 This European Standard does not apply to products for pressure vessels and products for which other EURONORMS exist or European Standards dealing with steels for general structural applications are being prepared: - Hot-rolled products of non-alloy structural steels - (see EN 10025). - Semi-finished products for forging in general purpose structural steel - (see EURONORM 30). - Weldable fine grain structural steels - (see EN 10113 Parts 1 - 3). - Plates and wide flats made of high yield strength structural steels in the quenched and tempered or precipitation hardened condition -(see EN 10137 Parts 1 - 3) - Structural steels with improved atmospheric corrosion resistance -(see EN 10155) - Steels for shipbuilding - normal and high strength qualities - (see EURONORM 156) - Hot finished structural hollow sections (see EN 10210-1).
