ULTIMET^® alloy

A colbalt-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.

Isocorrosion Diagrams*

The isocorrosion diagrams shown on this page were plotted using data obtained in laboratory tests in reagent grade acids. These data should be used only as a guide. It is recommended that samples be tested under actual plant conditions.

Resistance to Hydrochloric Acid	Resistance to Nitric Acid


Resistance to Sulfuric Acid	Resistance to Phosphoric Acid

Corrosion rates in parentheses are in mm/year. * All test specimens were heat treated at 2050°F (1121°C), water quenched and in the unwelded condition.
