Dillimax 690T and Dillimax 890T are ultra high-strength quenched and tempered steel plates engineered for extreme performance under dynamic loads. Manufactured by Dillinger in Germany, these proprietary steels are widely used in cranes, heavy lifting equipment, and structural frames where both strength and low weight matter.
With yield strengths of 690 MPa and 890 MPa respectively, these plates offer superior load-bearing capacity without adding bulk. They are trusted across Europe and globally for their tight thickness tolerance, excellent weldability, and fatigue resistance—especially in industries where safety, precision, and strength are non-negotiable.
Whether you’re a structural fabricator, EPC contractor, or OEM building demanding machinery, Dillimax 690T/890T plates ensure your projects remain lighter, stronger, and longer-lasting.
Dillimax 690T and 890T plates are precision-grade structural steels designed for:
They are ideal where lightweight, high-yield structures must handle dynamic forces and vibrations.
Dillimax 690T:
Dillimax 890T:
These properties allow structures to endure high bending and dynamic stresses with less material usage, improving both performance and design flexibility.
Carefully controlled alloying ensures weldability, strength, and toughness:
| Element | 690T (Max %) | 890T (Max %) |
|---|---|---|
| Carbon (C) | 0.18 | 0.20 |
| Manganese (Mn) | 1.70 | 1.70 |
| Silicon (Si) | 0.50 | 0.50 |
| Chromium (Cr) | 0.50 | 0.80 |
| Molybdenum (Mo) | 0.70 | 0.70 |
| Nickel (Ni) | 1.80 | 2.00 |
| Phosphorus (P) | 0.020 | 0.020 |
| Sulphur (S) | 0.010 | 0.010 |
| CE (Carbon Equivalent) | ~0.45 | ~0.48 |
This chemistry ensures good weldability, even with high strength, and reduces the risk of hydrogen-induced cracking during fabrication.
