UNS R31233

Short Description:

Highly weldable material UNS R31233(ULTIMET) provides a unique blend of properties. From a wear standpoint, it behaves like the STELLITE alloys with lower carbon contents. From a corrosion standpoint, it possesses many of the attributes of the C-type and G-type HASTELLOY materials, in particular outstanding resistance to chloride-induced pitting and crevice corrosion. Its mechanical and welding characteristics are much closer to those of the HASTELLOY alloys than those of the STELLITE alloys, whose low ductilities can be problematic. While ULTIMET alloy has been used successfully in the form of wrought products, its largest applications have involved weld overlays, made with solid wire consumables and arc welding processes such as GMAW (MIG) and GTAW (TIG).

UNS R31233 is a cobalt-based alloy with excellent resistance to galling, cavitation erosion, slurry erosion, liquid droplet impact. Ideal welding material with exceptional ductility and resistance to weld cracking, very easy to apply as an overlay, multiple layers applicable with little to no preheat.
