Hastelloy Alloy Threaded Flanges

Hastelloy Threaded Flanges are usually constructed from sophisticated nickel-molybdenum or nickel-chromium alloys like Hastelloy C22, C276, and B2. These alloys demonstrate superior resistance to aggressive oxidizers, reducers, and extremely corrosive chemicals like hydrochloric, sulfuric, and nitric acids. Their mechanical properties are also improved by the forging and threading process, such as tensile strengths of up to 760 MPa, and they have a leak-resistant, precise fit. They are also extremely resistant to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
