2 And is still in alloy electrogalvanizing rolls have beenused successfully in the production of galvanizedsteel for automobiles in the Far East and corrosion/wear rate of ULTIMET alloy in thisapplication is about half that of the previouslyused Ni-Cr-Mo cast nozzles are nowstandard for a major incineratorscrubber manufacturer inEurope. In this application, ULTIMET alloy has out-performed ceramics and castCo-Cr-W and Ni-Cr-Mo is the standardshielding material for fans usedby a large fiberglass companyin North America. It has provedresistant to erosion/corrosion infiberglass manufacturing, and ispreferred over the Co-Cr-Walloys because of its relativelyhigh FEATURESO utstanding Corrosion-Wear ResistanceULTIMET alloy is cobalt-chromium alloy which offersexcellent corrosion resistancecomparable to that of theHASTELLOY alloys . ULTIMET alloy exhibits outstanding wearresistance similar to that of theSTELLITE alloys . Also, ULTIMET alloy possesses hightensile strength comparable tomany duplex stainless steelscombined with excellent impacttoughness and alloy is an idealwelding material with excep-tional ductility and resistance toweld cracking.

3 It is very easy toapply as an overlay , comparedwith the traditional cobalt-basewear alloys . With ULTIMET alloy , cracking of the overlay isnot a consideration, and mul-tiple layers may be applied, withlittle or no FormsULTIMET alloy is available inmost common wrought productforms: plate, sheet, billet, bar,wire, and covered forms of this alloy arefurnished in the solution heat-treated condition, unlessotherwise of Haynes Interna-tional produce ULTIMET alloyremelt bar for castings andULTIMET gas-atomized pow-ders for plasma transferred arc,plasma spray, and high-velocityoxy-fuel of the areas of use forULTIMET alloy are: Agitators Blenders Bolts Dies Extruders Fan Blades Filters Glass Plungers Nozzles Pumps Rolls Screw Conveyors Valve PartsField Test ProgramSamples of ULTIMET alloy arereadily available for laboratoryor in-plant corrosion testing. Ananalysis of the tested materialcan be performed and theresults provided to the customeras a technical service.
