Steels for quenching and tempering for construction purposes. Technical delivery conditions

Alkalmazási terület

This document specifies the technical delivery requirements for the following steel products intended for use in the construction industry: bars (including hammer-forged bars); wide flats; hot-rolled strip and sheet/plate; forgings. They are manufactured from the direct hardening non alloy steels for quenching and tempering and the direct hardening alloy steels for quenching and tempering and supplied in one of the heat treatment conditions given for the different types of products in Table 1. These steels are generally intended for the manufacture of quenched and tempered parts, but can also be used in the normalized condition. The requirements for mechanical properties are restricted to part sizes given in Tables 4 and 5. NOTE 1 In accordance with EN 10020, the steels covered by this standard are quality and special steels. The differences between quality and special steels are characterized by the following requirements, which are valid for special steels only: ? the minimum impact values in the quenched and tempered condition (for non alloy special steels in the case of mean percentages by mass of carbon < 0,50 % only); ? limited oxide inclusion content; ? lower maximum contents for phosphorus and sulphur. NOTE 2 This standard does not apply for bright steel products. NOTE 3 This standard only applies for the manufacture of products without any further cold or hot forming and no additional heat treatment, i.e. the properties are according to the delivery condition (+N, +QT). In addition to the specifications of this European Standard, the general technical delivery conditions given in EN 10021 will be applicable unless otherwise specified.
