These Duplex Manifold Valves are made from a blend of chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), manganese, and nitrogen, which together create a dual-phase microstructure of ferrite and austenite. This unique composition strikes an impressive balance between strength, toughness, and corrosion resistance. On the mechanical side, they boast a tensile strength ranging from 620 to 850 MPa and a yield strength between 450 and 550 MPa. Additionally, Duplex Manifold Valves are known for their exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, ensuring they remain durable and reliable even in high-pressure, high-temperature, and chemically aggressive environments.
