The nickel based Hastelloy C22 also offers optimum resistance in environments where the alloy will come across process streams in both reducing as well as oxidizing conditions. Crevice tests of Hastelloy C22 Ring Joint Type Flanges were performed in both still (quiescent) and flowing seawater, at 29 Degree C, plus or minus 3 Degree C. As is evident from the following results, Hastelloy C22 Nippo Flanges are much more resistant to this form of attack than the comparative, austenitic stainless steels.
