scope:

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 2 (chemical composition), 4 and 5 (mechanical properties) in het 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 1. The application of this standard to greater thicknesses shall be agreed at the time of the enquiry and order. 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.
