DescriptionIndustries and ApplicationsResistance to CorrosionFabrication and Heat TreatmentCommon Trade NamesAlloy 20 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 may provide potential cost savings when carefully compared to higher nickel-based alloys, while out performing standard stainless steels.CORROSION- RESISTANT NICKELALLOYScorrosion diagrams for B-3, C-2000, 400, and 625 al-loys are shown in Fig. 6 to 9.
