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.
