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..

In our proposal we apply our broad experience and network of referees, and when communicating to you, we look for options, which would result in a significant reduction of your costs..

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

A special sintered tape (electrode) enables:

  • a large scale of alloying thanks to the production of powder metallurgy method
  • tailor made alloying according to a precise specification of customer
  • high flashing performance when applying the UP method
  • precise alloying specification (the chemical data of the wire composition correspond to the chemical composition of the hard deposit in the 1st layer already, thanks to the high speed and low intermixing)
  • economic production of small batched 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)
