Product Details
EN 10025-6 S690QL is a high-strength structural steel plate with a minimum yield strength of 690 MPa, designed for heavy-load-bearing applications requiring strength, toughness, and weight efficiency. Supplied in a quenched and tempered condition, S690QL provides excellent impact resistance, formability, and weldability, even at low temperatures.
These plates are used in engineering structures, lifting equipment, bridges, cranes, mining and earthmoving machinery, and offshore platforms, where performance under stress is critical.
