ULTIMET Alloy Tig GMAW-GTAW Solid wires




ULTIMET Alloy Tig

 
TYPE 
Cobalt-based solid welding wire for hardfacing / rebuilding
APPLICATIONS 
Wire can be used to weld ULTIMET wrought products and to overlay and clad carbon and low-alloy steels. The weld deposits harden very quickly by cold working. In addition, it is very easy to deposit a "crack-free" layer without a butter layer. The filler metal finish on the MIG wire is for a smooth feeding through welding equipment and reduces tip wear in contact tips.
PROPERTIES 

-ULTIMET wires easily produces crack-free weld deposits (over-matching weld overlays, weld inlays, and claddings). -It is easier tot weld with ULTIMET wire than traditional cobalt-based alloys, allowing multiple layer build-ups with no pre-heating needed. -ULTIMET wire produces deposits wich harden quickly through peening, machining, power hammering, burnishing, or hard particle impingement. This hardness creates a tough, ductile, wear-, corrosion-, and high-temperature resistant surface. The hardness of 30% cold-worked wrought product is approximately RC50. -ULTIMET deposits exhibit extremely high resistance to metal to metal galling and seizing. -The pitting resistance of ULTIMET alloy in chloride solutions is equal to that of HASTELLOY C-22HS alloy, and is greater than that of C-276 alloy.
