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.

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 .

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.

This is the main reason why Super Duplex Flanges note an improvement of tensile strength over ferritic and austenitic steel grades.

2205 has excellent corrosion properties, and it is well-suited to environments containing chlorides and hydrogen sulphide, for use in oil and gas extraction from sour wells, in refineries and in process solutions contaminated with chlorides.

The Benefits of Duplex Stainless Steel are improved Strength, because many duplex grades are as much as two-times stronger than austenitic and ferritic stainless steel grades, high Toughness and Ductility, high Corrosion Resistance, and Cost Effectiveness.

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

Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation.

Duplex 2205 stainless steel plate has excellent corrosion resistance, much higher than grade 316. It can withstand localized corrosion types such as intergranular, pitting and crevice.

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

 ANSI B16.5 Super Duplex Stainless Steel S32750 Orifice Flange provides excellent resistance to a wide range of corrosive environments, including seawater, acidic solutions, and chloride-containing environments. Super Duplex F53 WN Flange exhibits higher corrosion resistance than standard duplex stainless steels.

The Duplex Pipes are used in high temperature applications along with the Duplex stainless steel tube as well. There are different shapes and sizes of these pipes.

The material has high strength values. The minimum yield strength is 450MPa and the minimum tensile strength is 620MPa, with 25% minimum elongation and 290HB Brinell hardness.

The dual microstructure and chemical composition of ASME SA 479 UNS S32760 bar makes it a high performance alloy. Due to its designation as a superalloy, most manufacturers are aware of the very valuable mechanical properties of F55 UNS 32760 Hex Bar.

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.

Zeron 100 is highly resistant to corrosion in a wide range of organic and inorganic acids. The copper content gives excellent resistance to corrosion in many oxidising acids. This alloy is also highly resistant to strong alkalis.

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.

There are components of duplex 2205 fasteners available such as studs, set screws, bolts, washers and nuts. Whenever you specifically consider duplex stainless steel 2205 gaskets, it can be of great benefit for different types of critical industrial applications often found in harsh environments. Almost all types of 2205 stainless steel gaskets will provide a never-ending supply and excellent range of service for different applications such as valves or nuclear, seawater, offshore buoyancy and petrochemical, pumps, etc.

S32760 also has high strength and extended service life. It is 10% lighter than grade 316 steel, ideal for sub-zero use, and more cost-effective than nickel alloys. Stainless steel grade F55 can be easily machined and welded.

Astm A790 Uns S31803 grade pipes and tubes can be cold-rolled to give them enhanced properties and good resistances in different systems.

Both ASME B16.5 and ASME B16.47 have endorsed pipe flanges made from a series of duplex stainless steel grades.

Super Duplex tubes for the increasing hostile temperature and operating environments – where maximising operating efficiency demands total product reliability. 2507 Super Duplex Products therefore have very his corrosion cracking resistance and tensile strength.

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).

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.

For 2500# in sizes from NPS 1/2 to NPS 12 ASTM A182 UNS S32750 Flanges, with requirements in both metric and U.S. A182 S32750 Flat Flanges for companies involved in Equipment Manufacturing, Oil Refineries, Mining, Chemical manufacturing and Industrial Construction.

The yield strength of 2205 is about twice that of austenitic stainless steel. This allows designers to reduce weight and make the alloy more cost-competitive compared to 316L or 317L.

UNS S32750 Super Duplex Hex Nuts has been developed at the beginning of the century to cope with the increasing demand, across many industries, for more durable steels that could withstand demanding service conditions. The versatile and extensive range of UNS S32760 Super Duplex Hex Nuts reflects the differing lifestyles in every kitchen, accompanied with the proper faucet.

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.

HT PIPE is the government certified and doing business in steel industry for long years and are manufacturing S32750 Duplex buttweld fittings at affordable rates.

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.

It is a super duplex alloy, so heat resistance is also what Super Duplex 2507 rods are capable of. River or sea water often contains highly corrosive chemicals containing sulfur or chloride ions, and materials such as the 2507 Super Duplex Round Bar can withstand these chemicals.
