的区别。
EN 10025-2:2004, Hot rolled products of structural steels - Part 2: Technical delivery conditions for non-alloy
structural steels.
EN 10025-3:2004, Hot rolled products of structural steels - Part 3: Technical delivery conditions for
normalized/normalized rolled weldable fine grain structural steels.
EN 10025-4:2004, Hot rolled products of structural steels - Part 4: Technical delivery conditions for
thermomechanical rolled weldable fine grain structural steels.
EN 10025-5:2004, Hot rolled products of structural steels - Part 5: Technical delivery conditions for structural
steels with improved atmospheric corrosion resistance.
本人只看出化学成分的细微差别，无非是从2到5 杂质PS 等的控制严格了
请从交货状态，检验方法等方面区别给与支持.
谢谢各位大虾了！！！！
