Ultimet Applications

This alloy is widely used for various industrial purposes. Following are some of the uses of Ultimet:

  • This alloy has high corrosion resistance abilities. In fact its resisting abilities are comparable to that of the Hastelloy alloys. Hastelloy is the trademark name for 22 highly corrosion resistant alloys, all of which are produced by the Haynes International, Inc.
  • Ultimet is also a very efficient wear and gall resistant material.
  • The electrogalvanising rolls of this alloy are successfully used in the production of galvanized steel. This steel is used for automobiles In Europe and the Far East.
  • It is also commonly used in agitators, blenders, dies, fan blades, nozzles, glass plungers, valve parts and screw conveyors.
