Description
SUPER DUPLEX 2507 STAINLESS STEEL PIPE or super duplex 2507 pipe is a ferritic-austenitic (biphasic) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels because of their high levels of chromium and molybdenum The ability to resist pitting corrosion, crevice corrosion and uniform corrosion.The biphasic microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical strength is also high.
Typical 2507 Duplex Stainless Steel Microstructure
2507 stainless steel used in the oil and gas industry; offshore stone breaking oil platform (heat exchanger tubes, water treatment and water supply systems, fire protection systems, water systems, water stabilization systems; petrochemical equipment; desalination (desalination) equipment High-pressure pipe, sea water pipe); both high strength and high corrosion resistance of the mechanical and structural components; combustion (waste) gas purification equipment. Main components: 25Cr-7Ni-4Mo-0.27N
1. super duplex 2507 stainless steel pipe seamless
2. super duplex 2507 stainless steel pipe welded
3. super duplex 2507 stainless steel pipe fittings
4. super duplex 2507 stainless steel pipe flanges
5. super duplex 2507 stainless steel valves
SAF 2507 has a high compressive strength, impact strength and low coefficient of thermal expansion and high thermal conductivity. These features apply to many structural parts and mechanical parts. SAF 2507 impact strength is high, not long-term placed Higher than 570 ° F in the temperature environment, this may weaken its toughness. Tensile strength: σb ≥ 730Mpa; Elongation: δ ≥ 20%
Supporting welding consumables: ER2594 welding wire, E2594 electrode
Applications: pulp and paper industry, desalination, flue gas purification, heat exchangers, chemical tanker piping systems, seawater systems.

SUPER DUPLEX 2507 STAINLESS STEEL PIPE WELDED SUPPLIERS,MANUFACTURERS ,CONTACT KCM SPECIAL STEEL TO GET AMAZING PRICE AND HIGH QUALITY SUPER DUPLEX 2507 STAINLESS STEEL PIPE.
Super duplex 2507 pipes are a type of duplex stainless steel pipe that has recently gained popularity in several industries.
These pipes are made from an alloy that contains both austenitic and ferritic stainless steels, giving them exceptional strength, resistance to corrosion, and high durability.
Super duplex 2507 pipes are particularly well-suited for use in harsh and corrosive environments, making them a popular choice for offshore drilling, petrochemical, and chemical processing applications.
Super duplex 2507 pipes contain approximately 25% chromium, 7% nickel, and 4% molybdenum. This combination of metals produces a unique microstructure that provides outstanding corrosion resistance.
The addition of molybdenum increases the pipe’s strength and resistance to pitting and crevice corrosion, while nickel enhances the pipe’s ductility and toughness. The high levels of chromium provide excellent resistance to oxidizing agents and corrosion caused by chlorides, making super duplex 2507 pipes an attractive option for use in saltwater and acidic environments.
One of the main advantages of super duplex 2507 pipes is their exceptional strength.
These pipes are designed to withstand high levels of pressure and stress, making them ideal for use in offshore drilling and chemical processing applications. Additionally, super duplex 2507 pipes have a high level of resistance to fatigue, making them suitable for use in applications that require repetitive cycling or high levels of stress.
Another key benefit of super duplex 2507 pipes is their outstanding resistance to corrosion.
The high levels of chromium, molybdenum, and nickel give these pipes excellent resistance to both general and localized corrosion, including pitting and crevice corrosion. This makes super duplex 2507 pipes an ideal choice for use in harsh and corrosive environments that can quickly deteriorate standard pipes.
Finally, super duplex 2507 pipes are highly versatile and can be easily customized to meet specific application needs.
They are available in a wide range of sizes, grades, and thicknesses, which can be configured according to the needs of a particular project. Additionally, super duplex 2507 pipes are compatible with various types of fittings and connectors, making them easy to integrate into existing systems.
In conclusion, super duplex 2507 pipes are an excellent choice for applications that require a high level of durability, corrosion resistance, and strength.
These pipes offer unique properties that other types of pipes cannot match, making them an attractive option for a wide range of industries.
As demand for reliable, durable and corrosion-resistant pipes continues to increase, super duplex 2507 pipes are likely to become even more popular in the years to come.
