Supreme strength wire with optimal alloy formula

Duroxite® 200 WIRE is designed for applications with severe abrasive wear and moderate impact up to 600°C (1100°F).
Duroxite® 200 WIRE forms overlay with primary chromium-rich carbides with co-existing refined multi-alloy carbides which provide a good combination of wear and impact resistance.

Superior ease and flexibility of repair

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. The application of Duroxite® 200 wire can be done quickly in all position application that allows welders to weld upside down.

Examples of applications

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, wear plates operating at high temperature in the steelmaking industry.

1) ASTM G65 is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.
2) ASTM G65 wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top surface through to the depth of 75% of
the overlay.
