This European Standard spe~fies requirements for plates and wide flats of high yield strength alloy special steels. Part 1 of this European Standard specifies the general delivery conditions. Part 2 of this European Standard specifies the delivery conditions for quenched and tempered steels in the grades and qualities given in table 1(chemical composition) and tables 2 and 3 (mechanical properties) of Part 2. Part 3 of this European Standard specifies the delivery conditions for precipitation hardened steels in the grades and qualities given in table 1 (chemical composition) and tables 2 and 3 (mechanical properties)of Part 3. The steels specified in this European Standard are especially intended for use in heavily loaded parts of welded structures such as bridges, flood gates, storage tanks, water supply tanks, buildings, crane structures, etc. for service at ambient and low temperatures. 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 exist or are being prepared: - Hot-rolled products of non-alloy structural steels - (see EN 10025). - Semi-finished products for forging in general purpose structural steels - (see EURONORM 30). - Weldable fine grain structural steels - (see EN 10113 Parts 1 - 3). - Structural steels with improved atmospheric corrosion resistance -(see EN 10155). - Flat products in high yield strength steels for cold forming - wide flats, sheet/plate, wide and narrow strip - (see EN 10149 Parts 1 - 3). - Steels for shipbuilding - normal and high strength qualities - (see EURONORM 156). - Hot finished structural hollow sections (see EN 10210-1).
