What’s up guys? This is Michael with Michael Talks Metal back for another talk on some Hastelloy today. 92% not subscribed who are watching. Anyone who is watching this right now and NOT subscribed, let’s change that, hit that little button here, subscribe. Please, and thank you.

Today’s topic is another of the Nickel based alloys….  Hastelloy C-22.   All Hastelloy alloys are produced by Haynes International or a licensee.  So what is Hastelloy C-22 ?

Well, it’s primarily Nickel with Chromium,  Molybdenum, Tungsten, and Iron as the major alloying elements.  The UNS designation for the chemical composition is N06022

A solid solution strengthened material and very ductile, it can be further strengthened by cold work and its non- magnetic in the annealed condition at room temperature….

With excellent corrosion resistance in  many aggressive chemical environments and its resistance to both oxidizing and non-oxidizing corrosion;  this alloy is often used in chemical processing reactors and heat exchangers. It also finds applications in marine environments where crevice or pitting corrosion is an issue. Higher Chromium content provides additional corrosion resistance to oxidizing environments as compared to C-276.
