The Alloy 20 is an austenitic niobium-stabilized alloy that contains nickel and low carbon. The chemical composition of Alloy 20 Flanges will mainly include nickel, chromium, and iron, along with some additional elements like molybdenum and copper. The Alloy 20 Flanges is known for its excellent corrosion resistance, even in harsh chemical environments. The Alloy 20 Pipe Flanges show great resistance capabilities in surroundings containing citric acids, phosphoric acids, sulfuric acid, and chlorides. The ASTM B462 Uns N08020 material is known for its good mechanical properties, even at elevated temperatures.
The ASTM B462 Flanges are also resistant to pitting and crevice corrosion in chloride and acidic medium. The niobium helps stabilize the ASTM B462 Alloy 20 Blind Flanges against sensitization, which helps prevent intergranular corrosion. The 20cb3 Alloy 20 Slip-On Flanges are also quite resistant to stress corrosion cracking, and they come with high fabricability.

The enhanced mechanical properties of the SB 462 Material make it quite popular in a wide range of industries. For example, the SB 462 Flange is widely used in pharmaceutical, food processing, and chemical industries. The SB 462 Uns N08020 is very much in demand in the plastic industries too. Manufactures of Incoloy Alloy 20 Weld neck Flanges suggest that these should be used in applications like mixing tanks, heat exchangers, etc.
