Alloy 20 Buttweld Fittings are made from a nickel-chromium-molybdenum-based alloy designed for excellent corrosion resistance, particularly in acidic environments. The composition includes approximately 20% chromium, 29-34% nickel, 3-4.5% molybdenum, and small amounts of copper, iron, and manganese. This combination provides resistance to sulfuric acid, phosphoric acid, and other corrosive substances. The mechanical properties of Alloy 20 include a tensile strength of 45-70 ksi, a yield strength of 25 ksi, and an elongation of 30%. These fittings are highly durable and suitable for industries requiring high resistance to stress and corrosion.
