適用范圍：1.1 This European Standard specifies requirements for long products and flat products of hotrolled non-alloy, base and quality steels in the grades and qualities given in tables 2 and 3 (chemical composition) and 4 and 5 (mechanical properties) in the usual delivery condition as given in 7.2.The steels specified in this European Standard are intended for use in welded, bolted and riveted structures, for service at ambient temperatures (subject to the restrictions described in 7.5.1).They are not intended to be heat treated except products delivered in the delivery condition N. Stress relief annealing is permitted. Products delivered in N condition may be normalized and hot formed after delivery (see clause 3).Note 1: Semi-finished products which are to be converted to rolled finished products conforming to this European Standard should be the subject of special agreement at the time of the enquiry and order. The chemical composition can also be agreed at the time of enquiry and order, however the values should be within the limits of table 2.Note 2: For certain grades and product forms suitability for particular applications may be specified at the time of the enquiry and order (see 7.5.3, 7.5.4 and table 6).1.2 This European Standard does not apply to coated products and products for which otherEURONORMS exist or European Standards dealing with steels for general structural applications are being prepared:— Semi-finished products for forging in general purpose structural steel - (see EURO-NORM 30).— Weldable fine grain structural steel - (see EURONORM 113).— Weathering steels for structural purposes - (see EURONORM 155).— Plates and wide flats made of weldable fine-grained structural steels in the quenched and tempered condition - (see EURONORM 137).— Flat products in high yield strength steels for cold forming - wide flats, sheet/plate, wide and narrow strip - (see EURONORM 149).— Steels for shipbuilding - normal and high strength qualities - (see EURONORM 156).— Hollow sections - (EN 10 xxx in preparation).
