S420ML hsla structural steel
High Yield Strength Steel Plate Products Description
S420ML high strength structural steel is a European standard alloy steel plate, S420ML high strength sheet metal implements EN10025 standard.
S420ML high strength steel sheet grade indicates: 'S' is structural steel; '420' is the yield strength value of 420; 'M' is thermomechanical rolling; 'L' is -50° impact.
S420ML high tensile steel plate is 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.
