  • ApplicationUsed extensively in tanks, heat exchangers, pickling systems, sulfuric acid handling units, chemical processing, and corrosive environments where resistance to stress cracking, pitting, and crevice corrosion is essential.
  • Construction: Produced with exact dimensional tolerance under hot-rolled or cold-rolled circumstances. Without sacrificing corrosion performance, Alloy 20 Plates can be cut, welded, shaped, and machined to meet project specifications.
  •  Material Properties & Grades: Alloy 20 (UNS N08020) is an austenitic nickel-iron-chromium alloy stabilized with columbium (niobium). It is appropriate for tough industrial applications because of its exceptional resistance to sulfuric acid, chlorides, and acidic conditions.
  •  Extra Features: It can be polished, pickled, annealed, or passivated. offers superior heat stability, formability, and weldability. When necessary for project compliance, plates can be provided with third-party inspection and mill test certificates.
