Bibliography

Part 5 of this European Standard, in addition to Part 1, specifies requirements for flat and long products of hot rolled steels with improved atmospheric 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 European Standard may be supplied are given in Table 1.In addition to prEN 10025-1:2003 the steels specified in this European Standard 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 described 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 prEN 10025-1:2003). Products delivered in +N condition can be hot formed and/or normalized after delivery (see clause 3).
