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.

These flanges have excellent resistance in acidic solutions such as nitric acid, sulfuric acid, phosphoric acid, etc. Additionally, our duplex steel flanges perform well in seawater and chloride solutions. Our experts are producing dual phase steel F60 flanges with excellent properties such as strong properties, higher tensile strength, durability, machinability, ease of manufacture, excellent surface finish and longer service life.

This alloy is especially useful in the -50¡ãF/+600¡ãF temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some restrictions, especially when used in welded structures.

It is listed in Material Group 2.8 according to ASME B16.5 and ASME B16.47.

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

ASME B16.5 Duplex Steel Forged Flanges are available in sizes from 1/8″ to 24″. Depending on the size, flanges are available in different pressure classes. Class 150 Duplex Pipe Flanges are the lowest pressure class up to 2500.

With an increased chromium content compared with F51 it offers improved pitting corrosion resistance.

They are resistant to general corrosion. We are suppliers of ASME SA182 Duplex Steel UNS S32205 Weld Neck Flanges to sea water and power generation equipment.

Duplex 2205 and Super Duplex 2507 stainless steel butt weld flanges feature a high yield strength that is twice the annealed yield strength of typical austenitic stainless steels such as 304 and 316 stainless steel butt weld flanges. Because of this, Duplex 2205 and Super Duplex 2507 steels are some of the most common duplex grades used for butt weld flanges, with Super Duplex 2507 butt weld flange being the more corrosion resistant grade of the two.

In addition to this standard duplex grade, there are super duplex and lean duplex grades. Flanges made of duplex steel fall under ASTM A182 F51 UNS S31803 and others. ASTM A182 specification covers components for pressure vessel grade applications. These duplex flanges can be used in high pressure and high temperature services such as boilers, condensers, heat exchangers, power plants, and petroleum industry applications.

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.

To be able to form a piping system, pumps, pipes, valves and various other equipment are connected together by so-called flanges. These flanges are almost always threaded or welded. Flanges are great because they can be easily inspected, cleaned, or any desired modification.

The base body of the DIN 1.4462 flange has both a ferritic and austenitic structure. The duality of their microstructure changes not only the mechanical properties but also their corrosion resistance properties. The chemical composition of UNS S31803 Socket Weld Flanges consists of 22% chromium, 3% molybdenum, and 5% to 6% nickel.

For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.

Duplex’s superior mechanical and chemical properties are offset by its formability difficulties. These grades are great for simple flanged connections for fixed services, but are less effective when forming complex metal shapes. Fortunately, machinability of dual-phase steels in complex and circular structures is not an issue in structural steels, given the widespread preference for simple mild steels in non-corrosive applications.

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).

Duplex steels have both ferritic and austenitic microstructures. Due to the excellent mechanical strength and electrical resistance properties, our flanges are widely used in different industrial applications such as petrochemical, chemical equipment, oil and gas processing, automotive, etc.

Dual-phase steel butt-welded raised face flanges provide excellent and consistent machinability for increased cutting speeds, reduced tool wear and set-up time.

Duplex 2205 is characterized by high resistance to chloride stress corrosion cracking, chloride pitting and crevice corrosion resistance, good general corrosion resistance, good sulfide stress corrosion resistance, high strength and good weldability and workability.

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). The service temperature of 2205 duplex stainless steel should be limited to below 600¡ãF. Prolonged exposure to high temperatures can make 2205 stainless steel brittle.

The range of Duplex Steel 2205 Orifice Plate Flanges covers all standard materials, sizes, grades and specifications. These duplex steel SAF 2205 flanges are widely used in various application industries such as oil and gas industry, chemical industry, engineering, etc. Ferrous and Nonferrous Metals is committed to providing our customers with consistent and reliable service that meets their needs and promotes continuous improvement of superior systems and quality.

Duplex steel butt welding flange forgings are difficult to form due to their high strength and work hardening rate. However, due to the presence of a large amount of stainless steel, the flange is highly resistant to seawater-related corrosion.

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

Super Duplex Flanges use pure quality alloys with mixed austenitic and ferritic microstructures and high molybdenum and chromium content. This superior chemical composition provides superior resistance and increased strength. The products we manufacture are used in a wide variety of applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

ASTM A182 F53 Flange is a high strength flange that has 550MPa minimum yield strength and 800MPa minimum tensile strength.

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

Duplex steel flanges are designed to improve resistance to pitting corrosion, high strength, stress corrosion, crevice corrosion and cracking. Duplex steel sliding flanges resist sulfide stress corrosion and chloride environments. Duplex steel flat flanges are an important part of the duplex steel flange family.

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.

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.
