A cobalt-based, solid wire, ULTIMET® wire is used to weld ULTIMET® wrought products, and more importantly, 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 RTW™ filler metal finish on the MIG-spooled wire promotes smooth feeding through welding equipment and reduce tip wear in contact tips.
- ULTIMET® wire easily produces crack-free weld deposits (over-matching weld overlays, weld inlays, and claddings).
- It is easier to weld with ULTIMET® wire than traditional cobalt-based alloys, allowing multiple layer build-ups with no pre-heating needed.
- ULTIMET® wire produces deposits which 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 RC 50.
- 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.
