High strength steel S690QL heat treatment - quenching and tempering

High strength steel S690QL is high yield structural steel produced in compliance with EN 10025-6. S690QL heat treatment uses the quenching and tempering process and S690QL steel has good bending and welding properties.

As S690QL heat treatment is quenching and tempering, S690QL steel is also called S690QL quenched and tempered steel, or S690QL QT steel. High strength steel S690QL is used in a variety of sectors including: machine building, lifting equipment, vehicles and transport equipment, steel constructions, etc.

S690QL heat treatment is very important. The quenching and tempering heat treatment brings S690QL steel good combination of strength and toughness, and good comprehensive properties.
