Alloy 20, also commonly referred as UNS NO8020, is a high alloy special stainless steel grade with excellent resistance to sulfuric acid and chloride stress corrosion cracking. The alloy contains nickel, chromium, molybdenum and copper contents which together help in providing excellent general corrosion resistance. Because of good resistance to corrosion, crevice corrosion, and pitting, this stainless steel alloy is widely used for manufacturing tanks, heat exchangers, process piping and pickling equipment.A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. The term “flange” is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily.
