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
The technical details of S690QL are outlined below.
The grade designation of S690QL are the following:
- S = Structural Steel
- 690 = minimum yield strength (MPa)
- Q = Quenching & Tempering
- L = Low notch toughness testing temperature
