Duplex Steel UNS Grade S32205 Duplex Steel is resistant to chloride environments and sulfide stress corrosion. Its yield strength is approximately twice that of standard austenitic stainless grades. Duplex steel UNS S32205 flanges are extremely durable and can also be easily installed to any size thanks to the different shapes and sizes available.

The applications include high corrosive applications including acidic applications due to the material composition.

Duplex stainless steel grades are named duplex because these duplex flange equivalent grades have a two-phase microstructure. This two-phase microstructure consists of ferritic and austenitic stainless steel-like grains. As the name suggests, the duplex construction gives this duplex stainless steel socket weld flange material a variety of attractive properties.

The oxidation resistance of these dual phase steel S31803 butt weld flanges is good at high temperatures, but tends to become brittle at temperatures above 300 degrees Celsius, brittle after only 2 hours of exposure at 475 degrees Celsius. These dual phase steel S32205 ring joint flanges also feature high corrosion and erosion fatigue performance as well as lower thermal expansion and higher thermal conductivity than certified.

Duplex and Super Duplex Welding Flanges are ideal for critical applications involving high pressure, sub-zero and high temperature, as well as conditions where fluctuations cause expansion/contraction of the pipeline, and its main feature is that it is suitable for high pressure applications.

Other applications for 2205 flanges include use in marine and other high chloride environments, biofuel plants, pulp and paper industry – digesters, bleaching equipment, stock handling systems, and food processing equipment. Major industries using these Duplex 2205 flanges include asphalt upgrading plants, nuclear power (mostly seamless), heavy oil refineries, and petrochemicals and acids.

2205 flanges are highly resistant to pitting and crevice corrosion, perform well in most corrosive environments, and have good weldability. Specifications These dual phase steel S31803 butt weld flanges have good oxidation resistance at high temperatures, but tend to become brittle at temperatures above 300 degrees Celsius and only 2 hours exposure to 475 degrees Celsius.

The chemical composition of Duplex F51 flanges contains carbon, chromium, manganese, molybdenum, nitrogen, nickel and phosphorus. Flanges are used in pressure systems and valve fittings.

UNS S32205 ASTM A182 flanges have good resistance to chloride pitting and crevice corrosion due to a combination of chromium, molybdenum and nitrogen. The exotic duplex 2205 flange alloy is used in oil and gas exploration, this alloy is also used in the chemical processing sector.

S31803 has been supplemented by S32205 which has a higher minimum N, CR and Mo.

Stainless steel grades with more than 12% chromium in the alloy are resistant to the effects of oxidation. In the case of super duplex stainless steel 2507, its alloy contains 25% chromium, which improves oxidation resistance even at high temperatures.

A182 F51 Duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

Use of duplex and super duplex stainless steels should be limited to below 570¡ãF, as prolonged exposure to high temperatures can make the material brittle.

As with all stainless steel grades, the corrosion resistance of a metal or alloy depends primarily on the composition of the metal, in this case stainless steel. For resistance to chloride pitting and crevice corrosion, the content of elements such as chromium, molybdenum and nitrogen is considered to be the most important.

This grade, with a tighter specification, is captioned as F60, equating to UNS S32205. Consequently, S32205 can be dual-certified as S31803 but not vice-versa.

Sizes range from ?” to 48″. Pressure ratings range from 150 psi to 2500 psi and more. There are also different types of flanges for different applications. ASME SA182 F51 RTJ flanges have two rings as two halves that are joined at the joint by welding.

2205 flange has good sulfide stress corrosion resistance and high strength and good fatigue resistance.

Super Duplex Flanges are highly weldable. This alloy can be easily welded by various welding operations. These super duplex flanges are known for their high fatigue strength and provide high strength at moderate temperatures in the lower temperature range.

Duplex steel Werkstoff No 1.4462 threaded flanges also cannot be used below -50¡ãC as it will cause a ductile to brittle transition. Duplex UNS S32205 Orifice Flange has a tensile strength of 1,16,000 psi 800 MPa. Whereas the duplex SAF 2205 socket weld flange has a yield strength of 80,000 psi 550 MPa. The 2205 Duplex Butt Weld Flange is a low carbon version that is not affected by sensitization and avoids carbide precipitation in welding applications.

These flanges can be hardened by heat treatment. The application industries of duplex steel flanges are; they are used in offshore oil drilling companies, aircraft exhaust manifolds, petrochemicals, power generation, gas processing, pharmaceuticals, specialty chemicals, burner pipes and spiral welded pipes for fuels, pharmaceutical equipment, Heat exchangers, and seawater equipment. Duplex steel flanges are available in a variety of designs such as sleeve, butt weld, blind, threaded, lap joint and socket weld.

Pipe flanges are widely used as a popular category of pipe fittings. Flanges are used to mechanically connect two pipes together. It can also be used to mechanically connect pipes to tees, valves, chokes or any other device. Flanges are available in round, square and rectangular. In some cases, flanges are usually ring-shaped or plate-shaped to form a rim at the end of the pipe when fastened to the pipe.

Due to the alloy’s excellent resistance to dilute hydrochloric acid, Super Duplex 2507 flanges can be used in the chemical processing industry. Another common problem with steel alloys is that they tend to corrode during welding. When the alloy is welded, the temperature is high, and the excess carbon atoms are precipitated to form carbide precipitates.

Duplex steel flanges are often used for heavy duty welded components. We produce these flanges using high quality raw materials. Our customers trust us in the quality of our products as we continuously strive to improve our technology and provide impeccable products and services.

Butt welding flanges are drilled (machined), and the wall thickness of the flange is the same size as the matching pipe. The lighter the tube, the larger the diameter, and conversely, the heavier the tube, the smaller the diameter. Our range of butt weld flanges, butt weld flanges are typically used for high pressure, low temperature or high temperature.

Super Duplex Steel 1.4410 Flanges are having low alloying costs as compared to the similar ferritic and austenitic grade along with resistant to corrosion in the chloride-containing atmosphere because of well-enhanced yielding and tensile strength.

It also greatly increases the strength as the most effective solid solution strengthening element. Nitrogen is a strong austenite former, and the addition of nitrogen greatly improves the toughness of dual-phase steels. It also delays the formation of intermetallic compounds enough to allow processing and fabrication of dual-phase steels. Nickel is an austenitic stabilizer that promotes the formation of the austenitic FCC structure, which contributes to the toughness of dual-phase steels.

The formation of intermetallic phases such as sigma phase in duplex steel flange flanges occurs in the temperature range of 600¡ãC – 1000¡ãC, and the decomposition of ferrite occurs in the temperature range of 350¡ãC – 500¡ãC ( 475¡ãC embrittlement).

Duplex steels have high resistance to various types of corrosion. Duplex Steel S31803 is an extremely corrosion-resistant, work-hardenable alloy. Duplex steel S31803 butt weld flanges have good high temperature properties.
