S690QL vs S960Q: 100% composition overlap. Very similar materials, likely interchangeable for most applications.
S690QL vs S960Q
Side-by-side chemical composition and mechanical property comparison.
Overview
S690QL
1.8928
High-strength quenched and tempered fine-grain structural steel with minimum yield strength of 690 MPa. Used for heavily loaded structures like mobile cranes, mining equipment, bridges, and pressure vessels.
S960Q
1.8941
Ultra-high-strength quenched structural steel — YS 960 MPa min. Near the top of EN 10025-6 range. Approaches tool-steel-level strength while remaining weldable (with strict preheat/interpass control). Used for the most weight-critical structural applications: mobile crane booms, mining equipment, military vehicles, and specialty trailer chassis. Significantly reduces section thickness vs S355.
