It has an extruded coating containing the alloy elements. The deposit offers a good balance of impact and abrasion resistance. Deposits are forgeable but not readily machinable. Duroxite® AP ELECTRODE has a good weldability which can be applied in all positions. Duroxite® AP ELECTRODE can be applied to carbon, low alloy, manganese steels or any other steels substrate. It is suitable for single and multiple-layer up to three layers deposit maximum.
Key Benefits
• Duroxite® AP ELECTRODE is a hardfacing electrode for all positions welding.
Typical Applications
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.
