The chemical makeup of Alloy 20 consists of about 32–38% nickel, 19–21% chromium, 2–3% molybdenum, 3–4% copper, and niobium for intergranular corrosion stabilization. These fittings have a tensile strength of approximately 620 MPa, yield strength of 275 MPa, and good ductility with elongation of about 30–40%. The alloy is resistant to pitting, crevice corrosion, and stress corrosion cracking, particularly in hot concentrated acid and chloride environments. Its austenitic character provides good mechanical properties and good weldability without danger of sensitization.
