Industrial equipment—from heavy machinery to mobile platforms—needs steel that’s both tough and lightweight. Understanding how advanced high-strength plates like JFE HITEN 780 LE and Dillimax 690T compare helps you make smarter design and procurement choices. These steels deliver exceptional strength-to-weight ratios and fatigue resistance, making them excellent alternatives to traditional high-yield alloys.
What Are JFE HITEN 780 LE and Dillimax 690T Plates?
- JFE HITEN 780 LE is a Japanese ultra-high-strength steel, engineered for yield strengths up to 780 MPa, optimized for excellent weldability.
- Dillimax 690T is a European high-yield structural steel (~690 MPa), known for its robustness and performance across construction and manufacturing segments.

Why These Plates Matter for Industrial Equipment
These plates offer advanced advantages that directly impact equipment performance:
- Higher strength-to-weight ratio—thinner structures with same or greater load capacity
- Improved fatigue resistance—ideal for cyclic or dynamic loading environments
- Optimized fabrication qualities—good weldability and lower distortion risk
- Space & weight savings—vital for electric, mobile, and aerospace-related platforms
Choosing between them depends on the specific loading, manufacturing, and performance demands of your equipment.
Key Considerations and Common Questions
Engineers and buyers often ask:
- How do these compare with S690Q or S960QL plates?
- What’s the difference in alloy chemistry and fracture toughness?
- What are the fabrication requirements—weldability, bending, heat treatment?
- What plate sizes and certifications are available?
This blog answers all that — guiding you in selecting the ideal steel grade for your industrial equipment application.

Mechanical Properties Comparison – JFE HITEN 780 LE vs Dillimax 690T
| Property | JFE HITEN 780 LE | Dillimax 690T |
|---|---|---|
| Yield Strength | ~780 MPa | ~690 MPa |
| Tensile Strength | 850–1000 MPa | 770–940 MPa |
| Elongation (%) | ≥14% | ≥13% |
| Impact Toughness (Charpy V) | Excellent at -40°C | Excellent at -50°C |
| Weldability | Excellent (low CEQ) | Very Good |
| Thickness Range | 6 mm to 80 mm (depending on availability) | 6 mm to 150 mm |
While JFE HITEN 780 LE offers a higher yield strength, Dillimax 690T delivers exceptional toughness at low temperatures, making each suitable for slightly different environments.
Applications Across Industrial Equipment Sectors
Both plates are used in high-stress, load-bearing components of:
- Mobile cranes & lifting platforms
- Excavators and earth-moving machines
- Mining & drilling rigs
- Construction trailers & structural supports
- Hydraulic press frames & transport frames
- Railway & bridge structural reinforcements
Their high yield strength allows lighter designs without compromising performance—leading to lower dead weight and higher fuel efficiency.
Welding, Cutting, and Fabrication Ease
