Super Duplex Alloy UNS S32750 (F53 / 1.4410 / Alloy 32750 / Alloy 2507) combines the most desirable characteristics of both ferritic and austenitic steels.

Super Duplex UNS S32750 bar has excellent resistance to stress corrosion cracking in chlorine containing environments. After heating to a solution treatment temperature of 1080¡ãC to 1120¡ãC, quenching is required.

The most widely used stainless steel alloy is duplex 2205. It is also known as Duplex 2205 or Duplex 2205. It has ferritic and austenitic properties, making it ideal for environments with strong corrosion resistance. Good strength is a primary requirement. Duplex 2205 studs are essentially just a piece of threaded rod, in some cases, they are all designed to accept nuts, such studs are called stud bolts. It has excellent corrosion resistance and is superior to stainless steel 316 in most environments.

These super duplex UNS S32760 round bars are available in a variety of shapes, sizes and diameters depending on the needs and requirements of the application and customer supplied specifications. These super duplex UNS S32760 round bars are resistant to localized corrosion.

While Duplex 2205 is the most common duplex product we supply, we can also deliver Duplex 2304 and Duplex 2207 with reduced lead times as these alloys are stocked. Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel pipe with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

From corrosion resistance to strength, businesses around the world appreciate these properties of 2507 Super Duplex Seamless. Due to the dual microstructure phase, the weldability of this alloy is classified as good, which is why a relatively robust and durable super duplex welded pipe can be achieved.

Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength. Grade S31803 stainless steel was modified several times, resulting in UNS S32205, which was recognized in 1996. This grade provides higher corrosion resistance If we do not stock Duplex 2205 fasteners (imperial or metric), we can manufacture these to your specifications.

Technically, the microstructure of a duplex 2205 tube is approximately 50% ferrite and 50% austenite. As a result, the properties inherited from both categories make this nitrogen-enhanced duplex 2205 seamless pipe ideal for use in industries such as food processing, oilfield piping and heat exchangers, and flue gas desulfurization.

Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, and maintained 475 ¡æ brittleness, high thermal conductivity and Superplasticity of ferritic stainless steel. Compared with austenitic stainless steel, its yield strength is significantly improved, and its resistance to intergranular corrosion, stress corrosion, corrosion fatigue and abrasion is significantly improved.

2205 fasteners are widely used in applications requiring good corrosion resistance and strength. Has excellent corrosion resistance; much higher than other grades. It eliminates localized corrosion types such as intergranular corrosion, pitting corrosion and crevice corrosion. Duplex 2205 bolts are ideal for environments containing chlorides and hydrogen sulfide for oil and gas extraction from sour wells, refineries, and chloride-contaminated process solutions.

Also known as standard duplex stainless steel, these 2205 duplex bolts are one of the most widely used stainless steel grades.

Some of the advantages of using super duplex fasteners include its physical and excellent mechanical properties such as high yield strength, excellent tensile strength, high impact strength and excellent corrosion resistance.

The inclusion of chromium imparts good corrosion resistance to austenitic grade 304. However, increasing the chromium content to about 25%, as in the case of 2205 duplex stainless steel pipe makes the alloy resilient across several media.
