Duroxite 200 Wire is a hardfacing wire for welding to be used in applications to enhance the surface characteristics of parts subject to wear, erosion, or abrasion. The deposit is a matrix of hard complex carbides, offering superior performance in both fine and coarse abrasion applications. After welding stress-relief cracks naturally appear.

Duroxite® 200 Wire is ideal for single or double-layer deposits. Preheating, interpass temperature, and post-weld heat treatment should be applied as recommended for the base metal. When welding in downhill or uphill positions, it is recommended to reduce the wire feed speed and voltage.

Key Benefits

  • Consistent wear resistance from the surface to 75% of the overlay depth in multi-layer deposits.
  • Optimal alloy formulation forms a primary chromium-rich carbide with co-existing refined multi-alloy carbides.
  • Provides an excellent combination of wear and impact resistance.

Typical Applications

Duroxite® 200 Wire is primarily designed for hardfacing components subjected to intense wear from earth, sand, or abrasives at temperatures up to 600ºC (1100ºF).
Typical applications include sand and earthmoving equipment, ground-engaged teeth, slurry pipes, railway ballast tampers, dredge buckets and lips, sand dredging parts, dragline bucket liners, crushing equipment, components in the brick industry, coke hammers, rippers, sizing screens, Muller tyres, catalyst lift pipes, pump impellers, fan blades, rockwool rolls, wear plates, and other wear parts operating at high temperatures in the 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.

Test results for mechanical properties

Test results for mechanical properties, deposit overlay chemical composition, surface hardness, and ASTM G65-A weight loss were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, substrate chemistry and working temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended applications.

Fabrication and Other Recommendations

Welded overlay components can be processed through welding, cutting, forming, and machining. For specific recommendations, refer to the Duroxite® Product brochure or contact your local technical support representative.

Safety precautions

Welding or cutting Duroxite® products generates gases and harmful fumes that are chemically complex and challenging to categorize. The primary toxic substance in the fumes is hexavalent chromium. It is recommended to use proper exhaust ventilation systems, fume-extraction torches, and appropriate protective clothing and respiratory protection for operators. Duroxite® 200 Wire is a high-performance wire, combining the durability of wear-resistant welding wire with the strength of abrasion-resistant wire ideal for hardfacing applications in demanding environments.
