Postalloy® DuraHard™ 2828NCTi-FCO
Crack Free Titanium Enriched Hardface Alloy
Postalloy® DuraHard™ 2828NCTI-FCO is a non-cracking flux-cored, open-arc hardfacing wire that deposits a martensitic alloy with a high volume of finely dispersed Titanium Carbides (TiC). It has excellent abrasion resistance under low and high stress conditions and retains hardness at high temperatures. Crack-free deposits are possible with proper procedures. Use on carbon and low alloy steels.
- Excellent welding characteristics.
- Multiple layers maintain their hardness and abrasion resistance.
- Produces full slag coverage that does not require removal between passes. Slag is easily removed with a chipping hammer.
- Deposits are crack-free even after multiple layers.
- Cement rolls
- Hardbanding drill pipes
- Bucket pins
- Shredder & Fibrizer hammers
- Bucket teeth and lips
- Tillage implements
- Asphalt mixer paddles
