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

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 .

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.

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 steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

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.

Some steels also contain Mo, Cu, Nb, Ti, N and other alloy elements. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, and maintained 475 ¡æ brittleness, high thermal conductivity and Superplasticity of ferritic stainless steel. Compared with austenitic stainless steel, its yield strength is significantly improved, and its resistance to intergranular corrosion, stress corrosion, corrosion fatigue and abrasion is significantly improved.

2507 (UNS S32750) is a super duplex stainless steel designed for applications requiring excellent strength and corrosion resistance.

At temperatures above 300¡ãC, the brittle trace components of 2205 precipitate, and at temperatures below -50¡ãC, the trace components undergo a ductile-brittle transition; therefore, this grade of stainless steel is not suitable for use at these temperatures.

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.

Super Duplex SAF 2507 is a really strong material with great corrosion resistance.

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

Phase stainless steel UNS S31803 fasteners exhibit the properties of austenitic and ferritic stainless steels. UNS S31803 dual phase steel fasteners have high strength, good resistance to sulfide stress corrosion and excellent impact toughness.

ASTM A240 Type 2507 Super Duplex Plates must comply with ASTM A240. It is a specification of chrome and chrome-nickel stainless steel plate. Super Duplex 2507 plates are used in general applications and containers.

The A182 Gr. F51 / S31803 material is a typical duplex stainless steel, which contains approximately 50% ferrite and 50% austenite.

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.

Also known as standard duplex stainless steel, these 2205 duplex bolts are one of the most widely used stainless steel grades.

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

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).

Duplex 2205 alloy is composed of high chromium and low or moderate nickel conutenut.

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

ASTM A182 Super Duplex F55 Hex Bolts is used for Pumps, valves, chokes, Connectors, Pipework/flanges, Oil & Gas components, Manifolds, etc. The resulting savings in weight of ASME SA 182 Super Duplex S32760 Hex Bolts can dramatically reduce the overall cost of fabrication. Anneal Heat this ASME SA479 Super Duplex S32760 Hex Bolts to 1025 Degree C ¨C 1120 Degree C ensuring sufficient time is allowed for the centre to achieve furnace temperature and hold for a time commensurate with the ruling section, followed by water quenching.

2507 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid.

Zeron 100?contains 25% chromium and 7% nickel and 3.6% molybdenum along with copper and tungsten additions. Zeron 100 has a 50¨C50 austenitic¨Cferritic structure. It also has greater resistance to chloride pitting, crevice corrosion and stress corrosion cracking than exhibited by the standard 300 series stainless steels.

The properties of S31803 nuts are even double those of standard austenitic grades.

SA 815 S31803 Weld Fittings have exceptional chemical properties along with higher strength and good resistance to corrosion. Therefore this grade is used for fitting manufacturing. SA 815 S31803 Long/ Short Radius Elbow display outstanding resistance to pitting, crevice corrosion and have excellent weldability. They are perfect if one is looking for a sturdy pipe with good formability. ASME B16.9 WPS UNS S31803 Elbow also exhibits excellent resistance to acetic and marine environments.

The microstructure and composition of the duplex 2205 alloy provides corrosion resistance superior to Type 316 or 317 in many environments, and its minimum yield strength is more than double that of conventional austenitic stainless steels.

The S31803 fastener series demonstrates the properties of ferritic and austenitic stainless steels. These fasteners exhibit excellent resistance to crevice corrosion, stress corrosion cracking and pitting corrosion in harsh environments. In addition, these are excellent in resistance to chloride and sulfide stress corrosion environments.

Duplex alloys prove themselves useful in applications where ordinary steel grades are susceptible to failure. The microstructure of the Duplex Pipe Material partially consists of both austenite and ferrite regions.
