ASTM B729 UNS N08020 Nickel Alloy Seamless Pipe
UNS N08020(Alloy 20), is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. At 33% nickel, Alloy 20 has practical immunity to chloride stress corrosion cracking. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion.
Unlike regular stainless steel and steel grades, the UNS N08020 Seamless Pipe displays superior resistance to sulfuric acid, particularly when placed in aggressive environments, which could cause failure of the more conventional austenitic alloys.
