Composition analysis of S420M European standard high strength steel

S420M steel is a flat-rolled steel with a thickness of no more than 120mm that can be welded by thermomechanical rolling of fine-grained structural steel. S420M steel is also a high strength structural steel. The steel grade is composed 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 his delivery status, that is, the meaning of thermomechanical rolling. The impact of the rule when the temperature is not lower than -50 degrees is marked with a capital letter L.

S420M steel plate welding performance
The steel specified in the European standard EN10025-4 shall be suitable for welding.
 
S420M steel plates are suitable for heavy-duty parts of welded structures used in environmental and low temperature conditions, such as bridges, sluices, storage tanks, water supply tanks.
