Short Description:

High strength tension hot rolled pickled oil S235 S355 S420 S550 carbon steel slitted strip coil

S355 grade steel is a medium tensile, low carbon manganese steel which is readily weldable and possesses good impact resistance (also in sub-zero temperatures).

What is the difference between S275 and S355 steel?

S275 provides a lower strength (than S355) but has good machinability and can be welded. The average minimum yield for S275 steel is 275 N/mm² giving its name: S275. S355 is often used in the most demanding environments such as the offshore industry.

EN10149 S420MC steel plate/sheet,EN10149 S420MC steel plate/sheet, under EN standard, we can regard S420MC steel plate/sheet as high yield strength steels for cold-forming steels.

S420MC steel plate is mainly used as high yield strength steels for cold-forming steels.

The EN10149 S420MC steel is equivalent to SEW092 QStE420TM, NFA E420D, UNI FeE420TM, ASTM X60XLK and BS HR50F45 steel grades.
