rolled duplex coil coil prime quality 1.4462 plate

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.

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.

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

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 presence of ferrite in the duplex 2205 welded pipe is what provides for an enhanced performance of this stainless steel grade in caustic media containing environments.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

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.

The properties of duplex pipes include durability and high strength as well as their resistance to stress related corrosion cracking.

Stub ends are used with lap flanges. Metline is an ISO certified, PED approved duplex 2205 stub end manufacturer and supplier with a manufacturing base in India. We can supply both long and short ends (collars) with test certificate according to EN10204 3.1.

It reaches the phase balance of austenite and ferrite in roughly same volume fraction.

Compared with ferritic stainless steel and austenitic stainless steel, duplex stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.

The 2205 Duplex Stainless Pipe produced in accordance to ASTM A790 specification could be constructed by either a seamless construction or an automatic welding process.

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

ASTM A182 F51 equates to UNS S31803. This was the original caption for a 22% Cr duplex stainless steel.

These grades of super duplex stainless steel fasteners are used when applications require excellent corrosion resistance and strength. Composed of nitrogen, molybdenum and chromium, they have excellent resistance to crevice corrosion and chloride pitting.

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

Super Duplex UNS S32760 is one of the most common super duplex grades on the market. UNS S32760 is a duplex stainless steel designed for use in corrosive chlorine-containing environments, with the addition of W and Cu compared to UNS S32750.

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.

The ductility and corrosion resistance of duplex steel fasteners are reminiscent of their austenitic microstructure. On the other hand, the toughness and hardness of these fasteners are inherited from the ferritic region.

ASTM A240 UNS S32750 Plate is a stainless steel alloy with excellent resistance to chloride stress-related corrosion cracking.

Duplex steel UNS S32205 fasteners are used in the pulp and paper industry such as digesters, bleach plants and stock handling systems. Also known as WNR 1.4462 fasteners, they are developed and designed in our infrastructure to international quality standards to the highest quality standards.

Duplex describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase.

The SA 182-F51 S31803 comes under ASME B16.47, B16.48 and B16.5 standards with sizes ranging from 1/8 NB to 48NB.

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

The machinability of 2205 steel pipe is low due to its high strength. The cutting speeds are almost 20% lower than that of grade 304.

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).
