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.

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.

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 .

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

Super Duplex is composed of 24% to 26% chromium, 6% to 8% nickel, 3% molybdenum and 1.2% manganese, with the remainder being iron. Trace amounts of carbon, phosphorus, sulfur, silicon, nitrogen, and copper were also found in Super Duplex.

ASTM A479 Duplex Steel UNS S31803 Nuts have excellent general corrosion resistance in a variety of aggressive chemicals including seawater and industrial acids. The microstructure of ASME SA 479 Duplex Steel UNS S32205 Hex Nuts consists of a mixture of austenitic and ferritic phases. Therefore, it exhibits the properties of austenitic and ferritic stainless steels.

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.

They also have excellent resistance to corrosion cracking and localized corrosion such as pitting, intergranular and crevice. Unlike other standard austenitic steels, UNS S31803 steel has excellent magnetic properties.

Our duplex steel UNS S31803 fasteners are available in different grades such as industrial washers, industrial screws, stainless steel washers, stainless steel screws and more.

Super Duplex S32760 Bar proves to be an excellent replacement for austenitic grades in marine environments. Super Duplex S32760 round bar (ASTM A276/ ASTM A479) exhibits good heat resistance up to 300¡ã.

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

Duplex 2205 flanges offer good sulfide corrosion resistance, as well as chloride pitting and crevice corrosion resistant superior to 317L.

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.

ASTM A240 Duplex 2205 Sheets contains approximately 40-50% ferrite. Often referred to as the work horse grade 2205 is the most widely used grade in the duplex family of stainless steels.

Duplex steel UNS S31803 round bar is widely used for ferritic and austenitic duplex stainless steel bars.

ASTM A479 Duplex Stainless Steel 1.4462 Punched Gaskets are SCC resistant which is prominent in many applications such as hot water tanks, brewing tanks, desalination plants and processing plants. Therefore, ASTM A479 Duplex Stainless Steel UNS S31803 Lock Washers exhibit the properties of ferritic and austenitic alloys.

ASTM A240 Type 2507 Duplex Sheet is an alloy used in applications with high strength and corrosion resistance. The composition of the duplex 2507 sheet is approximately 25% chromium, 7% nickel and 4% molybdenum. This composition makes it resistant to crevice corrosion and chloride pitting.

The inclusion of chromium imparts good corrosion resistance to austenitic grade 304. However, increasing the chromium content to about 25%, as in the case of 2205 duplex stainless steel pipe makes the alloy resilient across several media.

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

Duplex steel sheets are resistant to chloride stress corrosion cracking at 150¡ãC.

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

Duplex stainless steels are approximately 50% ferrite and 50% austenite for optimum strength and corrosion resistance.

Duplex 2205 round steel contains 22% chromium, 3% molybdenum, and 5-6% nickel. In addition to excellent impact toughness and high strength, it also has high general, local and stress corrosion resistance.

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.

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

Super Duplex has all the benefits of other duplex steels, specifically the strength benefits of their biphasic structural composition of equal parts austenitic and ferritic stainless steel. This microstructure makes all duplex steels around twice as strong as regular single structure ferritic or austenitic steels, but Super Duplex has a higher chromium and molybdenum content, giving it considerably increased resistance to corrosion than its counterparts.

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

S32750 Seamless Pipes are chromium and molybdenum mixtures with high resistance to pitting. Many industries prefer these Seamless Pipes for their resistance to stress corrosion cracking and crevice corrosion.

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.
