Hard on wear, but easy to work and weld
DILLIDUR has been a fixed part of the global battle against cost-intensive wear for more than 50 years. Initial equippers and producers of wear-parts use these hardened proprietary steels with great success in many sectors, including earthmoving machinery and mining. Thanks to its decades of further development, DILLIDUR provides a unique combination of high resistance to wear and easy working and welding.
The strengths of DILLIDUR proprietary steel
- The steel composition of DILLIDUR, optimised to achieve high wear-resistance combined with pleasant working and welding, permits low preheat temperatures for welding and flame-cutting. This assures greater reserves in workshop fabrication and for on-site repairs under adverse conditions.
- DILLIDUR steels are available with hardnesses ranging from 325 to 550 Brinell to withstand maximum exposure to wear.
- Many thick-walled wear-exposed components, such as high-capacity shovels for punishing service in mines, for instance, need special resistance to cracking. The solution then is DILLIDUR IMPACT, a steel possessing verified extremely high toughness.
Steel Grade Overview
| Thickness (mm) | Nominal hardness Brinell | Special Feature | |
|---|---|---|---|
| DILLIDUR 550 | 10 - 51 | 550 | |
| DILLIDUR 500 | 8 - 100 | 50 | |
| DILLIDUR 450 | 8 - 100 | 450 | |
| DILLIDUR 400 | 8 - 150 (200) | 400 | |
| DILLIDUR 325 L | 6 - 50 | 325 | air hardened for higher service temperature or hot forming |
| DILLIDUR IMPACT | 40 - 150 | 340 | with enhanced crack resistance |
Reading the table: The nominal hardness of DILLIDUR 500 should read 500, not 50. The table uses grade names without the V or VAR suffix used in this page’s title.

Applications
Heavy plate for earthmoving machinery and mining
Mill text: Several paragraphs on this page come from Dillinger’s own literature, so “we”, “our” and “our customers” refer to Dillinger, not to Champak Industries.
Many leading manufacturers of earthmoving and mining machinery, around the entire globe, put their trust in Dillinger heavy plate? Because: anyone who produces machines that reliably achieve ultra-high performance under the most adverse service conditions, day in, day out, must also be able to depend on his partners' performance.
Dillinger's strengths in earthmoving machinery and mining
- Dillinger has for decades been - and today remains - a reliable supplier of plates that dependably possess the promised internal and external quality and properties and can be easily and reliably worked and welded.
- Our customers value our supply performance and future-orientated, long-term supply partnerships, with supply logistics, support and service all jointly harmonised with their specific needs.
- We supply a broad and diverse range of plates, extending from standard grades up to and including proprietary steels such as DILLIMAX, for ultra-high loads, and DILLIDUR, for optimised wear-resistance.
- We can also meet your individual specifications – and in formats and dimensions extending from the "routine" right up to XXL – and semi-fabricated, if you wish.
Heavy plate for mechanical engineering
Heavy-duty presses, tunnel-boring machines (TBMs) and rolling-mill technology – for challenging tasks like these, you need a partner that will supply you flexibly and reliably, in perfect harmony with the needs of your specific project. This is why Dillinger is the top address for mechanical-engineering specialists when they need heavy plate.
Dillinger's strengths in mechanical engineering
- We have consistently invested in the expansion of cost-efficient production facilities for thick and large-format plate, and are continuing to extend our market lead in this field with still more investments.
- Extra heavy precision-cut plate, individual specifications, or flexibility on delivery dates – we meet your requirements dependably, making your projects more accurately calculable.
- If you wish, we can semi-fabricate your order, and supply, for example, precisely fitting cut plates.
- Our long-established customers value constant and reliable contacts at both commercial and technical level. This creates the basis for mutually confident cooperation and joint optimisation of the supply partnership.

Choosing Dillidur 400V Plates
Dillidur 400V Plates is in the 400 HBW hardness class. Higher hardness generally lasts longer against sliding abrasion but is harder to bend, cut and weld; where parts also take heavy impact, a tougher, lower class can last longer.
| Class | Nominal hardness | Typical use | Forming and welding |
|---|---|---|---|
| 400 (this page) | About 400 HBW | Dumper bodies, chutes, hoppers, screens | Cold bending and welding with normal care |
| 450 | About 450 HBW | Buckets, liners and heavier wear parts | Larger bending radii; preheat thicker sections |
| 500 | About 500 HBW | Cutting edges, crusher and severe-abrasion liners | Limited forming; strict cutting and welding procedures |
Other Dillidur classes
Brands of the same class are comparable, not identical; confirm any substitution with the end user. See all brands on Wear Resistant Plates.
Cutting, Fabrication and Welding
Champak Industries describes full and part plate/profile supply and a plasma-cutting service. Thermal cutting softens a narrow edge zone, and thick or hard plate may need preheat before cutting. Weld with low-hydrogen consumables and the mill’s preheat and interpass limits; do not heat the plate above the mill’s tempering limit. See AR Plates for bending and drilling guidance.
Testing, Inspection Documents and Traceability
| Requirement | What to identify in the order |
|---|---|
| Mill test certificate | EN 10204 3.1 showing brand and grade, heat number, chemistry and hardness |
| Impact test | Charpy test temperature and minimum energy, if required |
| Traceability | Heat and plate number transferred to cut pieces |
