Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature Above 50¡ãC .

It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy.

2507 has good weldability and workability, and it’s widely used in desalination equipment, chemical process pressure vessels, piping and heat exchangers.

For 2500# in sizes from NPS 1/2 to NPS 12 ASTM A182 UNS S32750 Flanges, with requirements in both metric and U.S. A182 S32750 Flat Flanges for companies involved in Equipment Manufacturing, Oil Refineries, Mining, Chemical manufacturing and Industrial Construction.

Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.

Duplex Stainless Steel UNS S31803 Hex Head Bolts Hex head and threaded bodies are available.

The combination of chromium, molybdenum and nitrogen give Duplex 2205 flanges good protection from chloride pitting and crevice corrosion, which makes them useful for marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.

Duplex stainless steel fasteners are made from alloys with high chromium content and low to moderate nickel content.

Duplex alloys have some of the ferritic stress corrosion cracking resistance of common austenitic stainless alloys and many of the superior formability properties that are more cost effective than high nickel alloys.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

An austenitic-ferritic stainless variant with a higher stress corrosion cracking resistance in comparison to regular austenitic 304 and 316 stainless, but with a lower toughness and impact strength.

The 2205 was developed to provide excellent machinability. Control of composition and inclusion type improves chip formation and reduces tool wear, resulting in higher machining efficiency and lower tool costs.

The chemistry of this steel ensures better performance with higher mechanical properties in comparison to austenitic stainless steel pipes.

The formation of ASTM A479 duplex steel UNS S32205 tie rod consists of a pool of austenite surrounded by continuous ferrite phases. ASME SA 479 Duplex Steel UNS S31803 Tie Rods are hot worked in the temperature range of 1750¡ãF to 2100¡ãF. This is designed to reduce the depth used in fabrication, thereby reducing the weight of precise significance for items such as pressure vessels, structural functions, etc. As ASTM A479 dual phase steel for bridges, storage tanks, etc. UNS S32205 rebar has approximately twice the superior performance of SS 304 .

Flat and lock washers can be cut or stamped from sheet to customer specifications. Since 2205 combines high strength, excellent corrosion and stress corrosion cracking resistance with very good pitting corrosion resistance and low thermal expansion, this may be the right alloy for your project nuts, bolts, spacers and studs.

ASTM A240 Type 2507 Duplex Sheet is an alloy used in applications with high strength and corrosion resistance. The composition of the duplex 2507 sheet is approximately 25% chromium, 7% nickel and 4% molybdenum. This composition makes it resistant to crevice corrosion and chloride pitting.

The material has high strength and corrosion resistance. The A182 F53 material is used to make flanges ranging from 1/2 inches to 48 inches under different standards such as ANSI, ASME, DIN and other international standards.

S32760 was originally developed as a seawater resistant material for pump applications in the North Sea.

Heated from 1050¡ãC to 1150¡ãC and water quenched, this treatment of duplex steel UNS S31803 nuts ensures that all carbides are dissolved.

UNS S32750 Bolts are used for the assembly of two unthreaded components, with the assistance of a nut. UNS S32750 Bolts are known to have superior properties such as high tensile and yield strength.

The equivalent proportions of their existence make it possible for the alloy to express qualities reminiscent of each steel type. Take austenitic steels, where the most basic grade, like 790 steel duplex pipe, has substantial corrosion resistance properties.

Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength. UNS S31803 grade stainless steel was modified several times to form UNS S32205, which was approved in 1996. This grade offers higher corrosion resistance.

Super Duplex Steel Stud Bolt is available in lengths ranging from 2mm to 200mm and has high strength values as well. Super Duplex S32750 is the most common duplex ferritic, austenitic stainless steel grade used for producing stud bolts.

Super Duplex is used in gas and oil industry, on offshore platforms, chemical processing equipment pressure vessels and boilers, in heat exchangers.

UNS S32205 dual-phase steel round bar has excellent resistance to chloride stress corrosion cracking, high strength, can withstand brackish water or salt water impact, and high surface toughness.

The pressure-temperature ratings for ASTM A182 F53 flanges are the same as that for other duplex stainless steels.

Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation.

Compared to 317L stainless steel, duplex steel has excellent resistance to chloride pitting and crevice corrosion. The alloy has excellent corrosion resistance to seawater and most concentrations of sulfuric acid. In addition, it is resistant to sulfide stress corrosion cracking (sour gas environments)

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

The advantage of the dual-phase structure is that it combines the advantages of ferritic alloys (resistance to stress corrosion cracking and high strength) with the advantages of austenitic alloys (ease of manufacture and corrosion resistance).
