What is S690QL material specification

What is S690QL material specification? S690QL material is high strength structural steel produced in compliance with EN 10025-6 technical standard. The main S690QL material we supply is S690QL steel plate, which is quenched and tempered for heat treatment. S690QL material has good bending and welding properties.
