Super Duplex Steel 2507 is a high-strength duplex stainless steel alloy consisting of an equal microstructure of around 50% ferrite and 50% austenite. It has approximately 25% chromium, 7% nickel, 4% molybdenum, and nitrogen content, together providing excellent resistance against pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments. It has high tensile strength of the order 800–1,000 MPa and possesses excellent toughness and ductility. Its combined chemical composition and microstructure provide Super Duplex 2507 greater corrosion resistance than normal duplex and austenitic stainless steels.

Yes, Super Duplex Steel 2507 bars can be welded, but they require proper welding techniques and precautions to avoid issues like thermal distortion and cracking. It is recommended to use skilled welders and specific filler materials.
Super Duplex Steel 2507 bars provide excellent corrosion resistance, high strength, and resistance to pitting, crevice, and stress corrosion cracking, making them ideal for harsh environments.
Yes, Super Duplex Steel 2507 Bars can be used for underground applications due to their excellent corrosion resistance, high strength, and durability in harsh environments. They are suitable for piping, structural, and reinforcement applications in underground settings.
Super Duplex Steel 2507 rods and bars find extensive applications in demanding situations where corrosion resistance and mechanical strength are critical. Typical applications include offshore and subsea oil and gas equipment, chemical processing tanks, heat exchangers, and piping systems exposed to severe seawater and corrosive chemicals. In the marine sector, they find applications in shipbuilding and offshore platforms, whereas in power plants, they find application in cooling systems and condensers. Their high resistance lessens maintenance expenses and prolongs service life in situations where there are extreme temperatures and corrosive substances.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
