UNS S32205 Duplex Steel ASME SA182 Butt Weld Flanges are suitable for seawater and power generation equipment because their smooth surfaces can withstand temperatures up to 600¡ãF, while also having excellent flow characteristics.

Duplex steel flanges are widely used in the used engineering, machinery and automotive industries. Duplex Steel S31803 Lap Flanges are ideal for applications requiring better corrosion resistance than Type 316 and good high temperature strength. We have Duplex Steel S31803 / S32205 Flanges in stock. Duplex steel flanges are commonly used in chemical, petrochemical, and power industries.

Molybdenum increases resistance to pitting and crevice corrosion. However, its content in duplex stainless steels is generally limited to less than 4% because Mo is also a ferrite former and can lead to unwanted intermetallic phases. Nitrogen improves resistance to pitting and crevice corrosion.

Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel). The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.

F51 duplex stainless steel is especially suitable for use in the temperature range of -50¡ãF/+600¡ãF, and can also be used for lower temperatures under strictly limited conditions (especially for welded structures).

Some 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. 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.

The combination of chromium, molybdenum and nitrogen gives 2205 good resistance to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.

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.

S32205 is a dual-phase steel with nearly equal proportions of austenite and ferrite in its chemical composition. This combination makes the alloy stronger than standard austenitic steels. The Duplex Steel S31803 Ring Fitting Flange is a low carbon version and is immune to sensitization.

S31803 has been supplemented by S32205 (F60) which has a higher minimum Ni Cr and Mo.

Though it is important to keep in mind that pitting corrosion can be a concern in chloride solutions when oxidizing media is present. In these conditions, the passive (protective) layer of the Duplex 2205 material may be compromised in localized pitting may occur.

SA 182 F53 S32750 Flange is a super duplex stainless steel supplied in the hot worked and solution annealed condition.

They have a design that allows for the pipes to pass through the flange and locate the correct point for connection. The ASTM A182 grade F53 WNRF Flange has a welded neck raised face.

Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.

The granular structure of the duplex is a ferrite-austenite hybrid material with a higher strength-to-weight ratio than 304 or 316. It balances the weldability of austenite with pure ferrite and maintains good mechanical toughness in applications exposed to cooler ambient temperatures. Offshore/seawater applications are common uses of this type of steel due to its excellent stress corrosion cracking properties. Therefore, duplexes are often found in desalination and pressure vessel plants located in port cities.

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.

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.

Super Duplex UNS S32750 /F53 Flanges are made from a super duplex stainless steel grade that has 24% chromium, 3% molybdenum, 6% nickel and carbon, manganese, silicon, sulfur, phosphorus, nitrogen and iron in the composition.

This category of material includes grades 2205, F51, F53, and F60. Duplex stainless has increased in popularity over the years due to its excellent chemical and mechanical properties versus their basic stainless counterparts, given especially that the cost differences are minimal now as the availability has increased.

Duplex steel flange also offers Good weldability and workability, High energy absorption and Low thermal expansion.

Based on composition, materials can be classified as Standard Duplex, Super Duplex, and Lean Duplex. Duplex steel flanges are suitable for high pressure, high temperature and highly corrosive applications. Duplex is also cost effective and has recently been used and replaced by other material grades.

Duplex stainless steel flanges, these flanges have some excellent properties such as light weight, robust construction, accurate dimensions and more. We also offer these products in different grades such as Duplex Flanges, Duplex Flanges, Super Duplex Flanges and Super Duplex Flanges.

The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.

Duplex steel flanges are hardened alloys that are also very corrosion resistant. The microstructure of this steel consists of a mixture of ferrite and austenite phases. Therefore, they have the characteristics of both ferritic and austenitic stainless steels.

2205 helps users to avoid stress corrosion cracking that is typically seen with 316 and 317.

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

These super duplex steel UNS S32760 flanges are technologically advanced using premium materials under the guidance of skilled experts. They have outstanding features such as resistance to plastic deformation, wear resistance, chipping resistance, and good machinability.

Compared to the corresponding austenitic steels, they are more prone to precipitation of sigma phases, nitrides and carbides, leading to embrittlement and reduced corrosion resistance. Duplex steel pipe flanges are an ultra-steel suitable for use in highly corrosive conditions where very high mechanical strength is required.

Super Duplex Steel Flanges are ideal for service in severely corrosive environments such as offshore and marine applications. It is also particularly resistant to chloride SCC. Flanges provide equivalent pitting resistance, ensuring very good pitting resistance. All of our product ranges are strength tested, including pitting corrosion testing, toughness testing, chemical and mechanical testing, macro and micro testing, and more.

Butt weld flanges are the most popular type of high pressure pipeline flange. The tapered hub design of butt weld flanges provides an extremely strong connection, and butt weld flanges can be manipulated and bent repeatedly without compromising material and/or connection quality . Butt weld flanges also have the advantage of being highly resistant to extreme high and low temperatures.

The mechanical strength, corrosion resistance and low temperature toughness of the ASTM A182 F53 Flanges is higher than that of ordinary duplex stainless steels.

Super Duplex UNS S32760 Reducing Flanges have a strengthened microstructure, a result of added Nitrogen, allowing fabrication of thin and low-weight flanges that are easy on the pocket.
