S960QL is an ultra-high-strength structural steel plate manufactured as per EN 10025-6, offering a minimum yield strength of 960 MPa. Designed for engineers seeking maximum strength with minimum weight, S960QL enables the fabrication of slender yet durable structures that can handle extreme dynamic and mechanical stress.
It is quenched and tempered, ensuring high impact resistance even at low temperatures and outstanding weldability. Ideal for critical structures in cranes, defense vehicles, heavy lifting equipment, and offshore rigs, S960QL enables material reduction without compromising safety or performance.
Hindustan Steel Corporation stocks and supplies S960QL plates in India and abroad, with complete certification, mill traceability, and project-ready cut-to-size options.
S960QL plates are trusted by leading OEMs, EPC contractors, and fabricators for:
S960QL is ideal for applications where component thickness must be reduced to meet weight, efficiency, or design constraints.
Under EN 10025-6, S960QL achieves excellent structural performance with guaranteed low-temperature toughness.
| Property | Typical Value |
|---|---|
| Yield Strength (Min) | 960 MPa |
| Tensile Strength | 980–1150 MPa |
| Elongation | ≥10% |
| Impact Energy | ≥27J at –40°C (Charpy) |
| Hardness (Brinell) | ~260–290 HB |
✅ Performance is consistent across full thickness range, ensuring reliable results in every project.
The chemical makeup of S960QL is carefully optimized to deliver high strength without sacrificing weldability.
