Duplex Steel Valves are mainly made up of around 22% chromium, 5–6% nickel, and 3% molybdenum, with the rest being iron and a bit of nitrogen. This unique dual-phase microstructure, which combines ferritic and austenitic phases, provides excellent tensile strength, yield strength, and toughness. These valves are highly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides. Additionally, Duplex Steel Valves showcase remarkable fatigue resistance and thermal stability, ensuring reliable performance even under high pressure, high temperature, and chemically aggressive conditions, making them ideal for critical industrial applications.
