The deposit offers a good balance of impact and abrasion resistance. Deposits are forgeable but not readily machinable. The wire has been developed to operate in a smooth semi-spray transfer mode whilst welding in all positions. Duroxite® AP WIRE can be applied to carbon, low alloy, manganese steels or any other steels substrate The deposited overlay is magnetic on carbon and low alloy steels but not on manganese steels. Duroxite® AP WIRE is suitable for single and multiple-layer up to three layers deposit maximum.

 

Key Benefits

• Duroxite® AP WIRE is a hardfacing wire for all positions welding.
• The Duroxite® AP WIRE deposited overlay consists of medium alloy martensite for a good abrasion and impact resistance.

 

 

Typical Applications

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.
