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 .

A789 UNS S31803 and UNS S32205 are two grades of duplex stainless steel that are widely used in various industrial applications. These Duplex S31803 Seamless Pipes are known for their excellent corrosion resistance, high strength, and good weldability. A789 is a specification that covers seamless and welded tubes made from duplex stainless steel.

ASTM A240 Type 2205 Plate is a duplex stainless steel plate that is used extensively in various industries such as chemical processing, oil and gas exploration, and marine engineering. SA 240 GR 2205 Sheet is made from grade 2205 stainless steel, which is a combination of ferritic and austenitic steel.

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

The high oxidation resistance property of Grade 2205 is marred by its embrittlement above 300¡ãC. This embrittlement can be modified by a full solution annealing treatment. This grade performs well at temperatures below 300¡ãC.

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.

ASTM A789 / ASME SA789 covers grades of average wall thickness, or, if specified on the order, minimum wall thickness, of stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are suscep- tible to embrittlement if used for prolonged periods at elevated temperatures.

The material for UNS S32760 Stud Bolts is about 10% lighter when compared to grade 316 stainless steel. The Stud Bolt S32760 demonstrates high performance at cryogenic temperature settings as well. Which means that the ASTM A1082 UNS S32760 has good sub-zero notch ductility properties down to a temperature of minus 50¡ãC.

Due to the material composition, the strength and the corrosion resistance, these flanges are used in a variety of applications.

ASTM A479 UNS S31803 Duplex Steel Bolts are made of duplex stainless steel. Due to the high mechanical properties, cost effectiveness and corrosion resistance of ASME SA 479 UNS S32205 Duplex 2205 Bolts and other products in this grade, Duplex Steel is used as a replacement for most other steel types.

ASTM A240 UNS S32760 Plate is a super duplex stainless steel alloy for specific applications.

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.

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.

ASTM A479 Super Duplex UNS S32750 F53 Heavy Hex Nuts are kept together by a combination of their threads’ friction (by means of slight elastic distortion), a small widening of the bolt, and solidity of the components to be held together.

In general, duplex steel S31803 plate can be used as a replacement for the rather expensive stainless steel alloy grade 904L, as 2205 SS plate has similar properties but is less expensive in composition.

ASME SA 479 UNS S32205 Fastener is a corrosion resistant and high strength super alloy that can be used in low temperature ranges up to 1300 degrees Fahrenheit.

Duplex stainless steel 2205 alloy is a compound stainless steel composed of 22% 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.

The ASTM A790 Duplex Welded Pipes are an example of welded duplex pipe. There are different grades of duplex pipes with different mechanical properties. There are duplex, super duplex and lean categories in the Duplex Pipes varieties. The Seamless Duplex Pipes are both strong and is highly corrosion resistant.

Duplex steel alloys have the properties of austenitic and ferritic stainless steels. This is because they have nearly equal proportions of dual microstructural phases (austenite and ferrite) in the annealed condition.

Light gauges of 2507 material can often be used to achieve the same design strength of thicker nickel alloys. Duplex 2507 plate is suitable for applications requiring excellent strength and corrosion resistance. It contains 25% chromium, 4% molybdenum and 7% nickel.

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.

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).

It is a tee fitting with two outlets at a 90¡ã junction to the main line.

The chemical composition of 2205 Duplex Stainless Pipe consists of the elements being used in the following content i.e. – 22% chromium, 3% molybdenum and about 5 to 6% nickel. Because of the content, in terms of quantity of chromium present in the alloy of this grade, this stainless steel is also referred to as 22cr Duplex 2205 Pipe.

UNS S32205 nuts (also known as S31803) are manufactured from high-grade duplex 2205 stainless steel. Since this material is composed of at least 22% chromium, 6% nickel and 3% molybdenum it can withstand several unique types of environmental inflexibilities that other metals cannot such as corrosion, cracking, erosion, pitting and more. Super duplex stainless steel 2205 nuts also provide twice the mechanical strength compared to standard stainless steel.

S32750 Welded Pipes are used in offshore platforms, Mechanical and structural components, sea-water piping, Desalination Plants, Heat exchangers and chemical processing industries.

A Super Duplex 2507 Pipe has outstanding resistance to corrosive and oxidative media.

Duplex 2205 is a chromium molybdenum blend which combines properties of both ferritic and austenitic steels.

Duplex¡¯s premium mechanical and chemical properties are slightly offset by its difficulty in formability.
