Alloy 20 is a nickel-iron-chromium austenitic alloy developed for maximum resistance to acid attack, particularly sulphuric acid. This super alloy has a high resistance to corrosion, crevice corrosion, and pitting in chemicals containing phosphoric, sulphuric and nitric acids. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion.

Alloy 20 is a combination of high corrosion resistance with mechanical properties and easy fabrication. Although designed originally to be used in sulphuric acid related industries, Alloy 20 is now a popular choice for a range of industries that include food, pharmaceutical and plastics industries. Furthermore, this super alloy is used in mixing tanks, heat exchangers, metal cleaning and pickling equipment, and piping.

Forms of Alloy 20 :

  • Sheet
  • Plate
  • Bar
  • Pipe & Tube (welded & seamless)
  • Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lap joints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)
  • Wire.

Properties of Alloy 20:

  • High general corrosion resistance to sulphuric acid.
  • Good resistance to chloride stress corrosion cracking.
  • Excellent mechanical properties and fabricability.
  • Minimal carbide precipitation during welding.
  • Excels in resisting corrosion to hot sulfuric acids.

Applications of Alloy 20:

  • Synthetic rubber manufacturing equipment.
  • Processing of pharmaceuticals, plastics and organic and heavy chemicals.
  • Bubble caps.
  • Petrochemical process equipment.
  • Food and dye production.
