Material Notes:

Ultimet alloy is cobalt-chromium alloy which offers excellent corrosion resistance comparable to that of Hastelloy alloys. Ultimet alloy exhibits outstanding wear resistance
similar to that of the Stellute alloys. Also, Ultimet alloy possesses high tensile strength comparable to many duplex stainless stells combined with excellent impact toughness and ductility.

Some of the areas of use for Ultimet alloy are Agitatitors, blenders, bolts, dies, extruders, fan blades, filters, glass plungers, nozzels, pumps, rolls, screw conveyors, and valve parts.

A cobalt-base alloy with exceptional resistance to galling, cavitation erosion, slurry erosion, liquid droplet impact, and various forms of corrosive attack. ULTIMET alloy exhibits superior weldability and may be used to weld overlay critical surfaces to improve their resistance to corrosion-wear. The alloy is available in a variety of wrought forms, as well as castings and powders.
