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.
The steel is used in a variety of sectors including

- Heavy transportation
- Machine building
- Steel constructions
- Lifting equipment

Applications : Crane booms, mining and earthmoving equipment, bridges, material handling, trailers and agricultural equipment.
