Alpha Overseas(AOS) is one of the distinguished manufacturers that offer Alloy 20 Pipe Flanges, which is an austenitic nickel-iron-chromium based alloy with additions of copper and molybdenum. The nickel, molybdenum, copper and chromium content of Incoloy 20 Flanges contribute to its overall resistance to chloride on stress corrosion cracking and general pitting attack. In the chemical process market, key applications of Carpenter 20 Flanges are in sulphuric, phosphoric and nitric acid environments. Alloy 20 Slip On Flanges is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless. Although originally designed for use in sulphuric acid related industries, Alloy 20 Blind Flanges is now a popular choice for a wide variety of industries including the pharmaceutical, plastics, chemical, and food industries. Resistance to sulphuric acid is particularly exceptional but Alloy 20 Weld Neck Flanges shows useful resistance in phosphoric acid, nitric acid as well as in chloride environments. Alloy 20 Socket Weld Flanges has excellent general corrosion resistance to sulphuric acid and to chloride stress corrosion cracking. These Alloy 20 Orifice Flanges can be fabricated to produce: Mixing Tanks, Process Piping, Heat Exchangers and Pickling Equipment.
We offer high quality of ASTM B564 Alloy 20 Weld Neck Flange in many shapes and sizes at reasonable prices.
Alloy 20 Ring Type Joint Flanges has excellent resistance to hot sulphuric acid and resistant to intergranular corrosion in the as-welded condition. Superior finishes in these Alloy 20 Slip On Flanges may be obtained using set-up and process speeds and feeds normally employed in austenitic stainless steels.
