What is the S690QL steel?

S690QL steel plate is a quenched and tempered high-strength steel plate. "S" means that its grade is European standard, and the corresponding national standard is Q690E high-strength structural steel. This steel is mainly used in the manufacture of low temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc.

S690QL steel plate characteristics:

S690QL uses controlled rolling technology. It can be seen from the chemical composition of the steel that the content of harmful elements S and P is relatively low, indicating that its steel is pure and has good welding performance.

Delivery status: quenching and tempering (quenching + tempering)

Note: Quenching and then tempering directly after hot rolling is considered equivalent to conventional quenching and tempering.
