Chrome Nickel Heat Resistant Alloy Nickel Welding Wire 

alloy 20 nickel welding wire ASTM B471    Alloy 20  was designed specifically to withstand sulfuric acid. Its nickel, chromium, molybdenum and copper levels all provide excellent general corrosion resistance. Restricted carbon plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post-weld heat treatment.   Alloy 20 is a highly alloyed austenitic stainless steel developed primarily for use in the sulfuric acid related processes. Alloy 20 is used is a wide variety of applications from Sulfuric acid pickling tanks, racks and heating coil, Heat Exchangers, Process piping, Chemical and petroleum process equipment etc. Alloy 20 Specification UNS W.Nr N08020 2.4660   Alloy 20 Chemical composition Grade…
