Duroxite® AP Wire is a gas shielded flux cored all positions hardfacing wire for components experiencing metal-to-metal wear, metal-to-earth wear, impact, and high abrasion applications. The deposit offers a good balance of impact and abrasion resistance. Deposits are forgeable, but can only be machined with special tools. The wire has been developed to operate in a smooth semi-spray transfer mode whilst welding in all positions. The deposited overlay is magnetic on carbon and low alloy steels but not on manganese steels.
Duroxite® AP Wire can be applied to carbon, low alloy, manganese, and other steel substrates. Duroxite® AP Wire is suitable for single and multiple-layer deposit up to three layers. Preheating, interpass temperature, and post-weld heat treatment are as needed according to base metal recommendations. If welding with downhill or uphill position, reduced wire feed speed and voltage are preferred to apply.
Duroxite® AP Wire has many applications where moderate/high impact and high abrasion wear conditions prevail. Examples: Bucket teeth, tillage tools, bucket lips, bucket sides, cutting edges, sand dredge equipment, dragline buckets, conveyor chutes, grizzly bars, screw flights, metal shredders, sliding metal parts, tire shredder knives, extruder screws, tamper feet, churn drills, muller tires. Especially applicable for all-positional welding and re-instating of hardfacing sealing runs on clad wear plate fabrications.
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.
Recovery: 90%
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, gases and harmful fumes are produced that are chemically complex and difficult to classify. The major toxic component in the fumes 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.
