Basic Information

• Product Name: 2507 Duplex Stainless Steel Pipes and Tubes
• Equivalent Grades2: UNS S32750, DIN/EN 1.4410, F53. In China, it is also known as 00Cr25Ni7Mo4N.

Chemical Composition10

• Main Elements: It contains approximately 25% chromium (Cr), 7% nickel (Ni), 4% molybdenum (Mo), and 0.24 - 0.32% nitrogen (N). The high chromium content provides good basic corrosion resistance. Molybdenum enhances the resistance to pitting and crevice corrosion, especially in chloride - containing environments. Nickel helps improve the strength and corrosion resistance of the material, and nitrogen further increases the strength and hardness.

Performance Characteristics

• Excellent Corrosion Resistance9: It has extremely good resistance to uniform corrosion, pitting, and crevice corrosion, especially suitable for chloride - containing environments such as seawater, oil and gas extraction, chemical industry, and paper - making industry. It also has strong resistance to organic acids such as formic acid and acetic acid, as well as inorganic acids containing chlorides.
• High Strength9: Compared with traditional austenitic stainless steels, it has higher yield strength and tensile strength, which can reduce the structural weight while maintaining the necessary strength level.
• Good Toughness and Ductility9: The duplex structure provides better toughness and a lower brittle transition temperature than single - phase ferritic or austenitic stainless steels.
• Good Weldability12: It can be welded by various common welding methods such as arc welding and gas - shielded welding. During the welding process, it can maintain good mechanical properties and corrosion resistance.
• Other Properties: It has a relatively high thermal conductivity and a low coefficient of thermal expansion, as well as high resistance to erosion - corrosion and corrosion - fatigue.

Application Areas12

• Oil and Gas Industry: It is used to manufacture oil and gas well drill pipes, casings, and subsea pipelines, etc. It can resist corrosive media such as hydrogen sulfide and carbon dioxide in oil and gas to ensure the safe operation of equipment.
• Chemical Industry: It is used in the manufacture of reactors, heat exchangers, towers, and other equipment. It can resist various corrosive media in chemical production processes, improve the corrosion resistance of equipment, and extend its service life.
• Marine Engineering: It is suitable for the construction of offshore platforms, subsea pipelines, and marine equipment. Its excellent chloride - resistant corrosion performance ensures the stability and durability of equipment in marine environments.
• Desalination Plants: It is used in the manufacture of desalination equipment and seawater cooling systems, etc. It can resist the corrosion of seawater and ensure the stable operation of the system.
• Power Industry: It is used in FGD systems, utility and industrial scrubber systems, absorbers, and pipelines in power plants. It can resist the corrosive environment in these systems.
