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

 SUPER DUPLEX 2507 STAINLESS STEEL PIPE CORROSION RESISTANCE

1. Usual Corrosive

The higher chromium and molybdenum content of SAF 2507 has a strong resistance to overall corrosion of organic acids such as formic acid, acetic acid, etc. The SAF2507 alloy has a strong resistance to inorganic acids, especially those containing chloride The corrosion resistance.
Compared to 904L, SAF2507 has a stronger corrosion resistance to diluted sulfuric acid ions. 904L is an austenitic alloy that is designed to withstand pure sulfuric acid corrosion.
316L grade can not be used in hydrochloric acid environment, it may be subject to local corrosion or corrosion.

SAF2507 can be used for dilution of hydrochloric acid environment, has a strong anti-stain and anti-fissure corrosion ability.

2. intergranular corrosion

The lower carbon content of the nSAF 2507 greatly reduces the risk of carbide precipitation in the intergranular phase during heat treatment, and therefore the alloy has a strong ability to resist intergranular corrosion associated with carbides.

3. Stress corrosion cracking

The compound structure of SAF 2507 has a strong resistance to stress corrosion cracking. Due to its high alloy content, SAF 2507 has better corrosion resistance and strength than 2205.
Cracks in the construction and other aspects is almost inevitable, which makes the stainless steel in the chloride environment more susceptible to corrosion.

SAF 2507 has a strong ability to crack corrosion resistance. SAF 2507 containing 2000ppm chloride ion in the sulfuric acid corrosion curve 0.1 mm / year; Corrosion curve in hydrochloric acid 0.1 mm / year.

The PREN value of 2507 stainless steel pipe/tube is ≥ 40, with a typical value of approximately 41–42, making it a high-corrosion-resistant super duplex stainless steel pipe/tube.

ASTM A789 / ASTM A790 UNS S32750 Super Duplex Pipe 2507 Mechanical properties:

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.

After proper solution treatment of 2507 stainless steel, the microstructure of the steel is more ideal than the dual phase structure of alpha / gamma ratio of 50/50. When the solution temperature is above 1050 DEG C, the ferrite phase number increases with the increase of temperature, but because of the high nitrogen content, there is no significant change in the phase ratio below 1300. This steel without aging at different temperature (or heat effect), in the alpha + gamma matrix will be formed and delta gamma 2, x, R, alpha ` intermetallic phases and Cr2N oxide precipitates, because the carbon content of the steel is low (usually 0.01%-0.02%), so in general no carbide steel.

What is Super Duplex 2507 Stainless Steel Pipe?

UNS S32750 Super duplex pipe is 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.

2507 Super duplex pipe Saf2507 is 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 pipe contains 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.

what are the advantages of 2507 Super duplex pipe UNS S32750?

One of the main advantages of 2507 super duplex pipe uns s32750 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 pipe 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.

Availability Of 2507 Super Duplex Pipe UNS S32750 From KCM Special Steel

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.
