Structural steels with improved atmospheric corrosion resistance - Technical delivery conditions EN 10155:1993

Publication date:   Jan 1, 1998

Scope

1.1 This European Standard specifies requirements for long products and flat products of hot-rolled steels with improved atmospheric corrosion resistance (alloyed special steel according to EN 10020) in the grades and qualities given in tables 3 (chemical composition), 5 and 6 (mechianical properties) in the usual delivery condition as given in 7.2. The thicknesses in which products of the steel grades and qualities specified in this European Standard may be supplied are given in table 2. The application of this standard to greater thicknesses shall be agreed at the time of the enquiry and order. Option 1. The steels specified in this European Standard are intended for use in welded, bolted and riveted components which shall have enhanced resistance to atmospheric corrosion, 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 the N condition may be normalized and hot formed after delivery (see clause 3). 1.2 This European Standard does not apply to structural steels for use in the applications referred to in 1.1 for which specific EURONORMS exist or European Standards dealing with steels for general structural applications are being prepared: - non-alloy structural steels - (see EN 10025); - steels for simple pressure vessels - (see EN 10207); - non-alloy steel sheet and strip for pressure purposes - (see EN 10028 part 1 - 3); - reinforcing bars (not for prestressing) - (see prEN 10080) 1); - weldable fine grain structural steel - (see EN 10113 part 1 - 3); - hot finished structural hollow sections - (see EN 10210-1). 1. Draft is under discussion
