Adopt standard: S690Q steel EN 10025-6
Sell steel grade: S690Q steel plate, S690QL steel plate, S690QL1 steel plate
S690Q steel plate
S690Q is high yield strength structural steels grade in the quenched and tempered.
The symbol S is structural steel, 690 for the minimum yield strength in thickness under 50mm.
The Symbol Q mean the delivery condition in quenched and tempered.
S690q could be through the -20 temperature impact and the energy is 30J.
