S690 QL is a high yield structural steel grade produced in compliance with EN 10025:6:2004. The material is heat treated using the quench and temper process and has good bending and welding properties.
Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.
Please refer to the technical details below referring to S690QL. Grade Designation - S = Structural Steel
- 690 = minimum yield strength (MPa)
- Q = Quenching & Tempering
- L = Low notch toughness testing temperature
