Duplex Steel is carefully formulated with a unique mix of chromium, nickel, molybdenum, and nitrogen. This specific composition gives it an exceptional combination of high strength and excellent resistance to corrosion, including stress corrosion cracking. The material is significantly stronger than standard austenitic or ferritic stainless steels. This robust strength means components can be designed with thinner walls, offering both weight savings and impressive toughness for challenging environments.
