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. |
