EN 10155:1993

EN 10155:1993 is a standard published by the European Committee for Standardization (CEN). Its full title is "Structural steels with improved atmospheric corrosion resistance - Technical delivery conditions". This standard covers: 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.

EN 10155:1993 is classified under the following ICS (International Classification for Standards) categories: 77.140.10 - Heat-treatable steels. The ICS classification helps identify the subject area and facilitates finding related standards.

EN 10155:1993 has the following relationships with other standards: It is inter standard links to EN 10025-1:2004, EN 10025-5:2004, CR 10313:2000. Understanding these relationships helps ensure you are using the most current and applicable version of the standard.

EN 10155:1993 is associated with the following European legislation: EU Directives/Regulations: 97/23/EC; Standardization Mandates: M/071, M/BC/CEN/87/15. When a standard is cited in the Official Journal of the European Union, products manufactured in conformity with it benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation.
