JFE HITEN 780LE and 690LE are high-strength quenched and tempered steel plates developed by JFE Steel Corporation, Japan, for superior structural performance under demanding conditions. These proprietary steels are engineered for lightweight design, high weldability, and excellent impact resistance, especially in dynamic environments like construction, crane manufacturing, and heavy mobile equipment.
Known for their tight tolerances, fine grain structure, and superior flatness, JFE HITEN plates are widely adopted in Japan, Southeast Asia, and now globally. The “LE” stands for Low-temperature Toughness and Excellent weldability, making these plates a trusted choice for projects involving sub-zero service conditions.
Hindustan Steel Corporation supplies JFE HITEN 780LE / 690LE plates in India, fully certified and cut-to-size, with fast export support.
JFE HITEN LE-series plates are suitable for load-intensive, weight-sensitive, and fatigue-critical applications, including:
Engineers select HITEN plates when they need performance beyond generic EN or ASTM steels.
JFE HITEN 780LE and 690LE deliver excellent strength, ductility, and impact resistance.
| Property | 780LE | 690LE |
|---|---|---|
| Yield Strength (Min) | 780 MPa | 690 MPa |
| Tensile Strength | 830–980 MPa | 770–930 MPa |
| Elongation | ≥15% | ≥16% |
| Impact Energy (–40°C) | ≥47J (average) | ≥47J (average) |
| Brinell Hardness | ~240–260 HB | ~220–240 HB |
Both plates meet or exceed performance of EN 10025-6 equivalents like S690QL or S780QL
The LE-series uses clean alloying to ensure excellent weldability and toughness.
| Element | Typical % (Max) |
|---|---|
| Carbon (C) | 0.18 |
| Manganese (Mn) | 1.60 |
| Silicon (Si) | 0.30 |
| Chromium (Cr) | 0.50 |
| Nickel (Ni) | 1.80 |
| Molybdenum (Mo) | 0.50 |
| Phosphorus (P) | 0.015 |
| Sulphur (S) | 0.005 |
| CE (Carbon Equivalent) | ~0.45–0.48 |
Plates are highly weldable with low hydrogen procedures, and grain-refined for uniform performance.
JFE HITEN 780LE and 690LE are proprietary Q&T steels manufactured by JFE Steel Corporation (Japan). While not governed by EN or ASTM, they are widely accepted in global projects as functional equivalents to several international grades.
Equivalent Grades (Mechanical Match):
| Standard / Brand | Equivalent Grade |
|---|---|
| EN 10025-6 | S690QL / S890QL |
| SSAB (Sweden) | Weldox 700 / 900 |
| Dillinger (Germany) | Dillimax 690T / 890T |
| ASTM (USA) | A514 Grade Q / F (approx.) |
| JFE (Japan) | HITEN 690LE / 780LE |
