S420M, S420ML steel plates are suitable for heavy-duty parts of welded structures used in ambient and low temperature conditions, such as bridges, sluices, storage tanks, water supply tanks, etc.
S420M, S420ML steel plate fulfills the standard: EN10025-4. S420M, S420ML steel plates are delivered in thermomechanically rolled condition.
S420M and S420ML are thermomechanically rolled and weldable fine-grained structural steels with a thickness of not more than 120mm. S420 is non-alloy structural steel, and the trademark of S420ML steel consists of the following parts: Symbol letter S: the yield strength value of structural steel with a thickness less than 16mm: not less than 420, M represents its delivery status, that is, thermomechanical rolling. The impact temperature is not lower than -50 degrees is marked with a capital letter L.
