The composition of Duplex Steel is a key to its strength, blending chromium, nickel, molybdenum, and nitrogen. This unique mix gives the check valve exceptional mechanical properties, including very high tensile strength and outstanding resistance to stress corrosion cracking. It stands up remarkably well to pitting and crevice corrosion, offering a far greater resilience than standard stainless steels. This results in a valve that is not only incredibly tough but also surprisingly cost-effective over its long service life.
