High Yield Structural Steel Plates

S690 QL is a high yield structural steel grade produced in compliance with EN 10025:6:2004. The material is heats treated using the quench and temper process and has good bending and welding properties.
- The code "S" for steel grade S690QL means structural steel.
- The code "Q"refers to the delivery condition, in this case to quenched & Tempered.
- The code "L" means that the average minimum values for impact energy have been defined at a temperature
of -40°C.
Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.

Chemical Composition :
