Incoloy® Alloy 020 Introduction
Incoloy® Alloy 020 is an alloy composed of nickel-iron-chromium, with additions of molybdenum and copper. These alloys are categorized as super alloys and exhibit excellent corrosion resistance and high strength. Some of the INCOLOY alloys are specifically made to resist selected reagents. These alloys are capable of functioning even at high temperatures.
INCOLOY alloy 020 exhibits excellent corrosion resistance in chemical environments that contain sulphuric acid, chlorides, phosphoric acid and nitric acid. It is easy to fabricate this alloy to form mixing tanks, heat exchangers, pickling equipment etc. The standard forms in which this alloy is available are round, flats, pipe, tube, strip and wire.
