Principal Features<\/h2>\n\n\n\n

STELLITE\u00ae<\/sup> alloy-like wear resistance and HASTELLOY\u00ae<\/sup> alloy-like corrosion resistance in a single, highly weldable material
<\/strong>ULTIMET\u00ae<\/sup> alloy (UNS R31233) provides a unique blend of properties. From a wear standpoint, it behaves like the STELLITE\u00ae<\/sup> alloys with lower carbon contents. From a corrosion standpoint, it possesses many of the attributes of the C-type and G-type HASTELLOY\u00ae<\/sup> 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\u00ae<\/sup> alloys than those of the STELLITE\u00ae<\/sup> alloys, whose low ductilities can be problematic.<\/p>\n\n\n\n

While ULTIMET\u00ae<\/sup> 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).<\/p>\n\n\n\n
