QStE420TM steel plate/sheet High yield strength for cold forming steels
SEW092 QStE420TM steel plate/sheet,SEW092 QStE420TM steel
plate/sheet, we can regard QStE420TM steel plate/sheet as high
yield strength steels for cold-forming steels.
QStE420TM steel plate is mainly used as high yield strength steels for cold-forming
steels.
The SEW092 QStE420TM steel is equivalent to EN S420MC, NFA E420D,
UNI FeE420TM, ASTM X60XLK and BS HR50F45 steel grades.
