Super Duplex 2507 Round Bar is a high-performance alloy made from a combination of both austenitic and ferritic stainless steels. With a balanced microstructure of approximately 50% austenite and 50% ferrite, Super Duplex 2507 combines the best of both materials—offering exceptional strength, corrosion resistance, and resistance to stress corrosion cracking (SCC). This round bar is engineered for use in extremely harsh environments, especially where exposure to aggressive chemicals and high pressures is common.

Super Duplex 2507 is composed of 25% chromium, 4% molybdenum, and 7% nickel, along with small amounts of nitrogen, which enhances its resistance to localized corrosion such as pitting, crevice corrosion, and stress corrosion cracking. With high tensile strength and excellent resistance to pitting corrosion in chloride environments, this round bar is ideal for industries such as oil and gas, marine, and chemical processing.

• High Strength and Durability: Super Duplex 2507 offers exceptionally high tensile and yield strength, making it suitable for high-pressure applications.

• Outstanding Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chlorides, acids, and seawater.

• Superior Resistance to Oxidation: With high resistance to oxidation at elevated temperatures, Super Duplex 2507 is well-suited for harsh, high-temperature environments.

• Good Weldability and Fabricability: Despite its high strength, the material retains good weldability and can be easily fabricated into complex shapes.

• Enhanced Fatigue Resistance: The combination of ferrite and austenite structure offers superior fatigue resistance, making it suitable for dynamic applications.

• Oil and Gas Industry: Piping, valves, and pressure vessels in offshore oil platforms, subsea systems, and deep-water drilling equipment.

• Marine and Offshore: Marine environments with high chloride content, such as seawater piping, seawater desalination plants, and offshore rigs.

• Chemical and Petrochemical Industries: Equipment exposed to aggressive chemicals, acids, and chloride solutions, including heat exchangers, reactors, and tanks.

• Power Generation: Components exposed to harsh environments, such as heat exchangers and condensers in power plants.

• Desalination Plants: Excellent choice for components exposed to seawater and other corrosive water environments.

Super Duplex 2507 round bars meet industry standards such as ASTM A276, ASTM A790, and UNS S32750, ensuring top-notch quality. These round bars are available in a wide range of diameters, lengths, and surface finishes to suit specific engineering and manufacturing requirements.
