S420ML steel

EN10113 S420ML steel plate/sheet,EN10113 S420ML steel plate/sheet, under EN standard, we can regard S420ML steel plate/sheet for Fine-grain structural steels, thermomechanically rolled steel.

EN10113 S420ML is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.Capital letter L for the quality with specified minimum values of values of impact energy at temperature not lower than -50 degree.It is equal to SEW083 TStE420TM,NFA36-201 E420FP and ASTM A633Gr.E
