Wire for Severe Abrasive Wear and Moderate Impact

Duroxite is SSAB's product brand for a wide range of overlay products in the form of overlay plates, overlay pipes, overlay pins and wire rolls for welding.

Duroxite overlay products are made of abrasion resistant materials deposited on top of mild steel or Hardox wear plate to create a wear resistant compound material. The latest addition to the Duroxite family is Duroxite 200 WIRE, which is a flux-cored welding wire for hardfacing various components.

"Duroxite 200 WIRE is mainly used for capping, routine maintenance or repair work. It can be welded on mild steel, Q&T steels, cast materials and stainless steel. Duroxite 200 WIRE is easy to apply on site or in the workshop. A common application is capping the weld when joining complex carbide overlay plates such as Duroxite 200 and maintaining the same service life as the plates. Duroxite 200 WIRE is self-shielded and welded with an open-arc process using manual or machine welding," said Lingyun Wei, Product Manager at SSAB. "When welding multiple layers of Duroxite 200 WIRE the same wear resistance is guaranteed from the surface down to 75% of the overlay thickness."

Duroxite 200 WIRE forms overlay with primary chromium-rich carbides with co-existing refined multi-alloy carbides, which, according to the company, provide a good combination of wear and impact resistance.

Duroxite 200 WIRE is designed for applications with severe abrasive wear and moderate impact up to 600 °C (1,100 °F). Typical applications include sand and earthmoving equipment such as buckets and teeth, railway ballast tampers, dredge buckets and lips, dragline buckets, coke hammers, rippers, sizing screens, crushing equipment, brick industry components, muller tires, catalyst lift pipes, pump impellers, fan blades, rockwool rolls and wear plates operating at high temperature in the steelmaking industry.
