EN 10025-5:2004 - Technical delivery conditions for structural steels with improved atmospheric corrosion resistance
EN 10025-5:2004 - European standard for hot-rolled structural steel. Part 5 - Technical delivery conditions for structural steels with improved atmospheric corrosion resistance
European steel grades designation systems. New standard EN 10025-5 : 2004 are similar but not identical to EN 10155:1993. Standard EN 10025:2004 published in six parts, here you can find steel grades and numbers for EN 10025-5:2004 - Part 5 standard:
