Alloy 20 Flange

Flanges produced from austenitic stainless steel grade Alloy 20 are covered by specification ASTM B462. Typically this specification covers alloys that have the ability to not only withstand elevated temperature settings but also those environments that contain highly corrosive compounds. One such instance is when the  Alloy 20 Flange is used to combat problems associated with the use of metals in sulfuric acids. Most stainless steel grades have very little to zero tolerance when concerned with applications involving sulfuric acid. Since alloy 20 has good resistance to sulfuric acid, in addition to phosphoric, and nitric acids as well as chlorine stress related corrosion cracking, the UNS N08020 Blind Flange is used to shut off or block off a nozzle in a vessel or a pipeline, without fear of the flange getting corroded or decayed.

Its resistance to several chemicals makes the ASTM B462 Alloy 20 Weld Neck Flange well suited to be used in conjunction with equipment for applications involving Synthetic rubber manufacturing, Petrochemical process, processing of pharmaceuticals, plastics as well as organic and heavy chemicals. Regarded to be a superalloy, this Alloy 20 DIN 2.4819 Reducing Flange is reminiscent of heat resisting properties similar to that of nickel based alloys. Aside from conforming to the chemical composition requirements of the ASTM B462 specification, the Alloy UNS N08020 Slip On Flange is required to conform to the mechanical requirements such as elongation, tensile and yield strength in addition to the testing requirements for tests like hydrostatic, macroetch, as well as tension tests.
