Duroxite® AP Wire is a wear-resistant welding wire specifically designed for hardfacing applications. It is intended for use with open arc welding, creating a durable surface layer that resists heavy wear, erosion and impact. The deposited material strikes a good balance between impact and abrasion resistance. While the deposits are forgeable they can only be machined with specialized tools. This wire is engineered to perform in a smooth semi-spray transfer mode and is suitable for welding in all positions. The overlay deposit is magnetic on carbon and low alloy steels, but not on manganese steels.
Duroxite® AP Wire can be used on carbon, low alloy, manganese, and other steel substrates. It is suitable for both single and multi-layer deposits, with up to three layers. Preheating, interpass temperature control, and post-weld heat treatment should be applied based on the base metal’s specifications. When welding in either downhill or uphill positions it is recommended to reduce the wire feed speed and voltage for optimal application.
Key Benefits
- Duroxite® AP Wire is a hardfacing wire designed for welding in all positions.
- The overlay deposited by Duroxite® AP Wire is made of medium alloy martensite, providing excellent abrasion and impact resistance.
Typical Applications
Duroxite® AP Wire is ideal for applications that experience moderate to high impact and significant abrasion wear. Some examples include bucket teeth, tillage tools, bucket lips, bucket sides, cutting edges, sand dredging equipment, dragline buckets, conveyor chutes, grizzly bars, screw flights, metal shredders, sliding metal parts, tyre shredder knives, extruder screws, tamper feet, churn drills, and muller tyres. It is particularly well-suited for all-position welding and restoring hardfacing sealing runs on clad wear plate fabrications.

Test results for mechanical properties
Test results for mechanical properties, deposit overlay chemical composition and surface hardness 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
The welded overlay components can be processed through welding, cutting, forming, and machining. For detailed recommendations, refer to the Duroxite® Product brochure or consult your local technical support representative.
Safety precautions
When welding or cutting Duroxite® products, gases and harmful fumes are released, which are chemically complex and difficult to categorize. The primary toxic substance in the fumes is hexavalent chromium. It is recommended to use proper exhaust ventilation systems and fume-extraction torches, along with appropriate protective clothing and respiratory protection for operators. Duroxite® AP Wire is an excellent choice for applications that require welding consumables offering superior abrasion and impact resistance. This premium, high-performance wire is specifically designed for wear-resistant overlays and metal-to-metal wear applications. Whether you need flux-cored wire or a hardfacing welding wire, Duroxite® AP Wire meets the highest standards for durability and wear protection.
