Alloy 20 Manifold Valves are crafted from a corrosion-resistant nickel-iron-chromium alloy, containing about 32–38% nickel, 19–21% chromium, 3–4% copper, and 2–3% molybdenum. This unique blend offers remarkable resistance to sulfuric acid, pitting, and stress corrosion cracking caused by chlorides. These valves boast impressive mechanical properties, with a tensile strength of around 551 MPa (80,000 psi) and a yield strength of 241 MPa (35,000 psi). Known for their excellent weldability, toughness, and durability in highly acidic and oxidizing conditions, Alloy 20 is the go-to material for manifold valves in aggressive chemical and process applications.
