Duroxite® 200 Wire
Download data sheet
Duroxite® 200 Wire is a flux-cored welding wire for hardfacing components subject to severe abrasive wear and moderate impact applications using an open-arc welding process. The deposit contains hard complex carbides in a tough matrix and performs exceptionally well for both fine and coarse abrasion applications. It naturally reveals stress-relief cracks after welding. Duroxite® 200 Wire is suitable for single-layer or double-layer.
Duroxite® 200 Wire is mainly designed to use for hardfacing components undergoing heavy wear by earth, sand or abrasives up to 600 ºC (1100ºF).
Typical examples include: Sand and earthmoving equipment, ground engaged teeth, slurry pipe, railway ballast tampers, dredge buckets and lips, sand dreging parts, dragline bucket liners, crushing equipment, brick industry components, coke hammers, rippers, sizing screens, Muller tyres, catalyst lift pipes, pump impellers, fan blades, rockwool rolls, wear plates or wear parts operating at high temperature in steelmaking industry.

1) Surface hardness is measured on machined flat surface just below overlay surface.
2) 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.
3) 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.

The welded overlay components can be processed by welding, cutting, forming and machining. Specific recommendations can be found in the Duroxite® Product brochure or by consulting your local technical support representative.
When welding or cutting Duroxite® products, smoke is produced containing harmful fumes and gases that are chemically highly complex and difficult to easily classify. The major toxic component in the fumes and gases produced in the process is hexavalent chromium. The proper exhaust ventilation equipment and fume-extraction torches are recommended, as well as suitable protective clothing and respiratory protection for operators.
