High Tensile Steel Plates for Crane Booms & Lifting Equipment
What Are Crane Boom-Grade High Strength Plates?
Crane boom-grade steel plates are ultra-high-strength quenched and tempered (Q+T) steels designed for telescopic booms, hydraulic arms, and lifting equipment. These plates combine extreme yield strength with light weight—essential for high-reach, mobile, and tower cranes where both load-bearing and safety are critical.
At Hindustan Steel Corporation, we supply precision-cut S690QL, S960QL, Weldox 700/900, and NAXTRA 70 plates to OEMs and crane boom fabricators worldwide.
High tensile steel plates power modern crane and lifting systems, including:
These plates reduce boom weight while enhancing safe load-bearing capacity, fatigue resistance, and weldability.
Crane steels must deliver high strength and flexibility under dynamic bending:
| Grade | Yield Strength | Tensile Strength | Elongation | Impact Test |
|---|---|---|---|---|
| S690QL | ≥690 MPa | 770–940 MPa | ≥14% | 27J @ -40°C |
| S960QL | ≥960 MPa | 980–1150 MPa | ≥10% | 27J @ -40°C |
| Weldox 700 | 700 MPa | 780–950 MPa | ≥14% | 27J @ -40°C |
| NAXTRA 70 | 700 MPa | 780–940 MPa | ≥14% | 27J @ -40°C |
Lightweight yet strong—perfect for boom reach, extension, and safe load lifting.
Typical chemistry for Q+T crane boom steels:
| Element | Max % |
|---|---|
| C | 0.20 |
| Mn | 1.60 |
| Si | 0.50 |
| Cr + Mo | ≤1.00 |
| S, P | ≤0.015 |
| Ni | Optional for toughness |
Optimized for fatigue resistance and high-strength weld joints in dynamic crane structures.
