The composition of Super Duplex Steel Forged Fittings includes high levels of chromium (around 25%), along with nickel, molybdenum, and nitrogen, all of which boost their mechanical strength and corrosion resistance. They boast impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly double that of standard austenitic stainless steels. Remarkably, these fittings maintain excellent toughness and ductility, even in sub-zero temperatures. Their advanced alloy composition guarantees strong resistance to localized corrosion, chloride-induced stress corrosion cracking, and erosion, making them a reliable choice for critical piping and process systems.
