Alloy 20 Tube Fittings are crafted from a unique nickel-iron-chromium alloy, enhanced with copper and molybdenum. Typically, the composition features 32–38% nickel, 19–21% chromium, 2–3% molybdenum, and 3–4% copper. This blend provides remarkable corrosion resistance, especially against sulfuric acid. With a tensile strength of around 551 MPa (80,000 psi) and a yield strength of 241 MPa (35,000 psi), these fittings also boast good ductility and impact resistance. Their ability to resist pitting and chloride stress corrosion makes Alloy 20 the go-to choice for aggressive environments where other stainless steels might falter.
