Primarily noted as C22, this hastelloy C22 is one versatile form of austenitic alloy, which comprises of its fair share of nickel, tungsten, chromium and molybdenum. This option will help in enhancing the resistance to putting, crevice corrosion and even stress corrosion based cracking. This higher chromium based content helps in providing good resistance to the oxidizing media, while you have tungsten and molybdenum content for providing that higher resistance to oxidizing the aqueous media. That will include mixtures and wet chlorine, which comprises of nitric acid or even oxidizing acids with the chlorine ions. This alloy is well resistant to wet chlorine, oxidizing acid chlorine, acetic and formic acid and even to sear water.
Application sources to cover:
Some of the major applications that you might care to address over here will be in pharmaceutical industries, where this alloy will be used in C22 Fittings and even tubing for avoiding contamination as caused by the corrosion related failures. Then you have cellophane manufacturing and even chlorinated systems, where you can easily get to see the wide uses of these forms of applications right now.
Other options to address:
There are some other options that you have to care and address when the matter is associated with Hastelloy C22 applications. In the field of pesticide production and even in incineration scrubber systems, you can see the wide use of this alloy and for so many good reasons. As this alloy is resistant to so many acids and materials, therefore; using the same in pesticide and pharmaceutical areas will work out just well for you. Then even in the waste water processing area, you can see the wide use of this alloy, which is designed to last quite long over here.
Help in chemical processing industry:
In case of Hastelloy C22 applications, you cannot deny the importance it holds in the chemical processing industry. There are so many types of equipment, which have been using this form of application to say the least. You have equipment in chlorinated systems, flue gas scrubbers, pulp and paper bleach plants, sulfur dioxide scrubbers and more, where you can see the use of this alloy for a long run. Then you have pickling systems and even the field of nuclear fuel reprocessing, where you can see the use of this application for sure.
Be sure of the fabrication:
Make sure to check out the fabrication of the alloy before you can use it for your service now. Even though the alloy is quite ductile, intermediate annealing might be quite necessary due to the work hardening. Forging needs to be performed between the 1750 to 2050 degree F, and then it is followed by the rapid cooling. Annealing seems to be performed at a temperature range between the 2020 and 2150 degree F. Be sure to know more about the options before coming to an end.
