Hastelloy Passivation

Hastelloy has superb sulfidation resistance and metallurgical stability, making it a preferable material for corrosive, high-temperature applications. Surface contaminants, however, can cause premature degradation if not removed.

With passivation services from Delstar Metal Finishing, Hastelloy component surface contamination is a non-issue. We safely and efficiently help eliminate embedded corrosion-causing contaminants as well as moisture- and bacteria-harboring microcracks and pits.


Why passivate Hastelloy?

Like other exotic nickel alloys, Hastelloy can degrade before use. Fabrication with carbon steel tooling or improper handling can kickstart contamination, diminishing part usability and lifespan. Passivation can reverse these adverse effects while enhancing corrosion resistance. 

Passivation of Hastelloy with the proper bath chemistry will remove contamination from the surface while supporting the formation of a protective oxide barrier. Further advantages include:


  • Extends The Product Lifespan
  • Removes Surface Contaminants
  • Lowers Maintenance Costs
  • No Discoloration
  • Environmentally Friendly
  • Superior Surface Cleanliness


Demanding applications, superior part performance 

Hastelloy is used in equipment designed to excel in extreme operating conditions. As a result, premature failure is not an option. Pickling and passivation of Hastelloy parts are advantageous for many industries.
