Union Ocel

CORODUR

The UnionOcel company specializes in effective solutions to improve abrasion resistance and offers a complex proposal to increase the lifetime of machinery equipment.

We are ready to deal with our customers' requirements to reduce production costs and offer COROPLATE, composite wear resistant plates, CORTHAL flux cored wires, THALOY and CORTHAL thermal spray coatings and COROSINT special sintered stripe electrodes.

In the vast majority of cases, usage of the aforementioned materialsextends the life expectancy of production machinery equipment as much as four times compared to the more commonly used abrasion-resistant steel materials, (e.g. XAR, Durostat, Dillidur, Hardox, etc.), thus significantly reducing the costs for repairs and increasing the efficiency of working and manufacturing processes.

The most common areas of application include:
  • SMELTING WORKS sorters, trays (it depends on what they smelt …)
  • POWER PLANTS coal, dust and ashes conveying
  • CEMENT PLANTS crushers, chutes
  • BRICKWORKS excavator buckets
  • QUARRIES chutes, excavator buckets
  • GRAVEL PLANTS loaders
  • BUILDING MACHINERY blades


When solving problems related to abrasion it does not apply that there would be a single universal material for all the equipment. In orther words, abrasion resistance is not a material property it is a system feature. This means that for each system there is a unique material and technical solution..

During the design phase, we leverage our extensive experience and references, and in our communication with you, we look for opportunities to significantly save your resources.

COROPLATE composite plates

COROPLATE Composite plates are produced by special π - welding method (powder injection.) This enables to delivery plates with a flatness guaranteed in accordance with EN10029 and the range of hardness up to 68 HRC. All plates are also supplied with an inspection certificate EN10204/3.1. This provides the possibility of its application in variety of industrial uses.

Sintered stripe electrodes

Special sintered tape (electrode) allows:

  • a wide range of alloying thanks to production by the powder metallurgy method
  • tailoring of alloying according to the customer's exact specifications
  • high deposition rate when using the SAW (submerged arc welding) method
  • precise alloying specification (data on the chemical composition of the wire correspond to the chemical composition of the weld overlay already in the 1st layer, thanks to high speed and low dilution!)
  • economical production of even small batches from approx. 50 kg


Standard dimensions and packaging

60 x 0.6 mm (weight of reel: max. 65 kg)

30 x 0.6 mm (weight of reel: max. 32 kg)
