The strength of these valves comes from their unique composition, a balanced mix of chromium, nickel, molybdenum, and nitrogen. This formula gives Duplex steel its renowned combination of high strength and excellent resistance to corrosion, particularly against stress corrosion cracking. They are significantly stronger than standard stainless steels, which allows for lighter and more compact valve designs without compromising performance or safety. This mechanical robustness makes them a dependable choice for handling challenging pressures and aggressive media, ensuring long-term reliability.
