Duroxite® AP Electrode is a solid cored electrode designed for components experiencing metal-to-metal wear, metal-to-earth wear, impact and high abrasion applications. It has an extruded coating containing the alloy elements. The deposit offers a good balance of impact and abrasion resistance. Deposits are forgable, but can only be machined with special tools. Duroxite® AP Electrode has a good weldability and can be applied in all positions.
Duroxite® AP Electrode can be applied to carbon, low alloy, manganese steels and other steel substrates. Duroxite® AP Electrode 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 feed speed and current are preferred to apply.
Duroxite® AP Electrode 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, 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.
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.
