22、has been prepared by Technical Committee ECISS/TC 10 “Structural steels - Grades and qualities”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2005,

23、and conflicting national standards shall be withdrawn at the latest by May 2005. This document supersedes together with EN 10025-1:2004, EN 10155:1993, Structural steels with improved atmospheric corrosion resistance - Technical delivery conditions. The titles of the other parts of this document are

29、eric corrosion resistance in the grades and qualities given in Tables 2 and 3 (chemical composition) and Tables 4 and 5 (mechanical properties) in the usual delivery conditions as given in 6.3. The thicknesses in which products of the steel grades and qualities specified in this document may be supp

30、lied are given in Table 1. In addition to EN 10025-1:2004 the steels specified in this document are especially 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 des

31、cribed in 7.4.1). The steels specified in this Part 5 are not intended to be heat treated except products delivered in the delivery condition +N. Stress relief annealing is permitted (see also the NOTE in 7.3.1.1 of EN 10025-1:2004). Products delivered in +N condition can be hot formed and/or normal

32、ized after delivery (see Clause 3). 2 Normative references The following referenced documents are indispensable for the application of this document.
