EN 10025-2 S690QL: High Strength Structural Steel for Demanding Applications
When it comes to designing structures or machinery that must endure extreme loads, heavy wear, and harsh conditions, material choice is critical. That’s where EN 10025-2 S690QL steel plates come in—engineered to deliver outstanding strength, reliability, and performance in the most demanding industrial environments.
Whether you're involved in infrastructure development, heavy engineering, or specialized fabrication, understanding the value of S690QL can give your projects the edge in safety, durability, and cost-efficiency.
What is EN 10025-2 S690QL Steel?
Though commonly referred to under EN 10025-2, S690QL is technically classified under EN 10025-6, a standard for high yield structural steels that are quenched and tempered. It offers an excellent strength-to-weight ratio, making it ideal for applications where lighter yet stronger materials are needed.
- S – Structural steel
- 690 – Minimum yield strength in MPa
- Q – Quenched
- L – Low temperature impact tested (typically -40°C)
In essence, S690QL is not just a steel plate—it's a high-performance engineering solution.
Where is S690QL Used?
Thanks to its high strength and toughness, EN 10025-2 S690QL steel plates are used in some of the world’s most demanding applications.
