characteristics of B462 Alloy 20 Flanges
Excellent corrosion resistance in reducing environments Excellent resistance to strong solutions of oxidising salts such as ferric and copper chlorides.
High nickel and molybdenum content for good corrosion resistance in reducing environments Low carbon content to minimise precipitation of grain boundary carbides during welding and in the heat affected zone of the weld joint Resistance to localised corrosion such as pitting and stress corrosion cracking one of the few materials that can withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide
B462 UNS N08020 Blind flange is a solid disc used to block off a pipe or create a stop.UNS N08020 Blind flange is machined in the same way as a normal flange, with mounting holes around the perimeter and gasket seals machined on the mating surface.
