Outstanding Corrosion-Wear Resistance
ULTIMET® alloy is a cobalt-chromium alloy which offers excellent corrosion resistance comparable to that of the
HASTELLOY® alloys. ULTIMET alloy exhibits outstanding wear resistance similar to that of the STELLITE® alloys. Also, ULTIMET alloy possesses high tensile strength comparable to many duplex stainless steels combined with excellent impact toughness and ductility.
ULTIMET alloy is an ideal welding material with exceptional ductility and resistance to weld cracking. It is very easy to apply as an overlay, compared with the traditional cobalt-base wear alloys. With ULTIMET alloy, cracking of the overlay is not a consideration, and multiple layers may be applied, with little or no preheat.
Product Forms
ULTIMET alloy is available in most common wrought product forms: plate, sheet, billet, bar, wire, and covered electrodes.
Wrought forms of this alloy are furnished in the solution heat-treated condition, unless otherwise specified.
Licensees of Haynes International produce ULTIMET alloy remelt bar for castings and ULTIMET gas-atomized powders for plasma transferred arc, plasma spray, and high-velocity oxy-fuel processes.
