Looking to source ultra-high strength quenched and tempered structural steel plates for demanding applications? Hindustan Steel Corporation offers a complete range of EN 10025-6 S690QL, S890QL, and S960QL Plates, engineered for strength, durability, and global compliance. With superior weldability, impact resistance, and high yield strength up to 960 MPa, these plates are ideal for use in heavy machinery, high-load frames, offshore structures, and mobile equipment.
As a trusted stockist, exporter, and processor, we supply from cut-to-size sheets to large-format quenched plates, with complete test certificates, mill traceability, and customized fabrication support. Whether you’re a manufacturer, EPC contractor, or OEM sourcing for international projects, our inventory is optimized to meet your specific dimensional, tolerance, and performance requirements.
EN 10025-6 defines a series of high yield strength structural steel grades, where:
These plates are low-alloy, fine-grain steels with excellent formability, even under extreme stress conditions, and are available with -40°C impact tested (Charpy V-Notch) guarantees.
Their strength allows weight reduction up to 30% compared to traditional mild steel without compromising safety or compliance.
| Property | S690QL/S890QL/S960QL | Mild Steel (IS 2062) |
|---|---|---|
| Yield Strength | 690–960 MPa | 250–350 MPa |
| Weight Efficiency | High | Low |
| Fatigue & Crack Resistance | Excellent | Moderate |
| Application in Mobile Units | Yes | Limited |
| Cost per Life-Cycle | Lower | Higher |
These steels deliver greater structural performance with less weight, allowing for reduced transport cost, leaner fabrication, and improved environmental footprint.
Hindustan Steel supplies plates that conform to EN 10025-6, with options to meet various national and global equivalents:
| EN 10025-6 Grade | DIN Equivalent | ASTM / ASME | Indian Equivalent |
|---|---|---|---|
| S690QL | WELDOX 700 | A514 Grade Q | SAILMA 700 HI |
| S890QL | DILLIMAX 890T | A514 Grade T | – |
| S960QL | DILLIMAX 960T | – | – |
All grades are delivered in tempered and quenched (Q+T) condition with 3.1 / 3.2 MTCs, CE mark (EN 10204), and Charpy impact test certifications as required by the project.
We maintain ready stock and custom processing capabilities for:
Weldable and bendable formats are offered with tight tolerances and minimal deviation for automated fabrication.
All S690QL/S890QL/S960QL plates are Q+T processed using advanced furnaces, achieving:
Plates are supplied with ultrasonic testing (UT) as per EN 10160 – S1E1 / S2E2.

| S890QL | Mining Equipment, Telescopic Booms | Higher Yield, Better Formability |
| S960QL | Lifting Beams, Offshore Rigs, High-Rise | Extreme Strength, Lighter Structures |
Not sure if S890QL is right for your boom loader? Our team offers design input and stress analysis help.
S690QL is used in cranes, bridges, construction equipment, and heavy structural applications due to its high strength and weldability.
‘QL’ indicates the steel is quenched and tempered with guaranteed impact strength at low temperatures.
S690QL has 690 MPa yield, while S960QL has 960 MPa. S960QL is stronger and used for lighter yet more load-bearing applications.
Yes. It requires controlled preheating, low-hydrogen electrodes, and proper heat input control during welding.
Typical composition: C ≤ 0.20%, Mn ≤ 1.7%, Cr ≤ 1.5%, Ni ≤ 2%, Mo ≤ 0.7%, with microalloying elements for toughness.
Yes. We can supply S960QL with CVN tested at -60°C (optional) as per project requirement.
We supply plates in 6mm to 150mm thickness, 1250–2500mm width, and lengths up to 12 meters.
EN 10025-6 governs S690QL, S890QL, and S960QL steel plate specifications.
Yes, it supports cold forming with proper radius control and edge conditioning.
Yes, S690QL is equivalent to A514 Gr Q in terms of mechanical performance and fabrication suitability.
Yes. We can arrange third-party inspection for 3.2 certification with agencies like Lloyd’s, TUV, DNV.
Yes. S690QL and S960QL are commonly used in offshore structural and marine load-bearing applications.
Dillimax is a branded form of S690QL by Dillinger. Both meet EN 10025-6 but may differ slightly in toughness and tolerances.
No. Q&T plates are for structural strength, not for pressure vessels. Use SA516 or A387 for boilers.
We maintain ready stock in Mumbai and deliver PAN India within 1–4 working days depending on location.
