Corresponding to the other nickel alloy grades, one of the main benefits of using Alloy C22, or what is also known as Hastelloy C22 is that the metal has one of the best corrosion resistance properties. This austenitic grade of Alloy C22 Seamless Pipe is able to resist corrosion, especially in oxidizing environments as it is able to resist corrosion in aqueous media as well. This particular resistance property of the Hastelloy C22 pipe proves to be rather beneficial to those factories that have upset conditions. More often than not, in chemical processing systems, the pipes need to encounter both reducing and oxidizing conditions (upset) at varying temperature levels.
