The Home of HASTELLOY® and HAYNES® alloys

Principal Features

STELLITE alloy-like wear resistance and HASTELLOY alloy-like corrosion resistance in a single, highly weldable material
ULTIMET alloy (UNS # R31233) 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).
