Super Duplex Steel Forgings typically contain around 25% chromium, along with nickel, molybdenum, and nitrogen, which boost both their mechanical strength and corrosion resistance. They boast impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly twice that of standard austenitic stainless steels. These forgings maintain excellent toughness and ductility, even in sub-zero temperatures, and effectively resist localized corrosion and stress corrosion cracking from chlorides, making them ideal for critical, high-pressure, and corrosive environments.
