Alloy 20 Pipe Fittings are crafted from a high-performance austenitic alloy, primarily made up of nickel (32–38%), chromium (19–21%), molybdenum (2–3%), copper (3–4%), and iron. This carefully balanced composition provides outstanding resistance to sulfuric acid, pitting, and stress corrosion cracking. The mechanical properties boast a tensile strength of about 620 MPa and a yield strength of roughly 300 MPa, along with excellent ductility and weldability. Ferdi Fittings’ Alloy 20 components undergo heat treatment and precise machining, making them perfect for demanding environments that require both corrosion resistance and mechanical strength.
