General Proprieties

Alloy 20 (UNS N08020) is a nickel-iron-chromium based, austenitic alloy with excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is stabilized with niobium to resist intergranular corrosion. Alloy 20 typical applications are: equipment for the manufacture of sulphuric acid and for processes based on sulphuric acid, extraction columns in the production of amines and the processing of pharmaceuticals , production of plastics and synthetic fibres , equipment for food processing to protect against contamination. This alloy is also know as Incoloy® 20. Alloy 20 is available at CHUN & VOLLERIN in these formats: Bars, Plates, Pipes, Stripes.
