Norwich Steel & Engineering Co. is one of the well-known traders of Alloy 20 Pipe Flanges, which has excellent resistance to chloride SCC. Alloy 20 Slip On Raised Flanges also has excellent resistance to crevice corrosion, weathering, and pitting. Chromium in Alloy 20 Blind Raised Flanges adds to its resistance of oxidizing environments, like nitric acid, and niobium reduces the effects of carbide precipitation. Alloy 20 Weld Neck Flanges is a super - austenitic alloy industrialized for supreme erosion conflict to sulfuric acid along with other aggressive atmospheres not appropriate for characteristic austenitic alloys. These Alloy 20 Socket Weld Flanges was designed for maximum resistance to acid attack and demonstrates superior resistance to SCC in boiling 20 percent to 40 percent of sulfuric acid. The corrosion resistance of our Alloy 20 Threaded Flanges also finds other uses in the power generation, plastics, chemical and petrochemical industries.
