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 .

With its myriad applications, the process industries are always in pursuit of highly reliable materials. Duplex Stainless Steel Piping is widely endorsed by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand the very aggressive fluids inherent in the process.

2507 Duplex Plate also exhibit better ductility and toughness compared to ferritic stainless steels, but they do not provide these properties as successfully as austenitic stainless steels.

Duplex UNS S32750 coils have very low corrosion rates under very high corrosive conditions.

2507 has good weldability and workability, and it’s widely used in desalination equipment, chemical process pressure vessels, piping and heat exchangers.

Super Duplex is used in gas and oil industry, on offshore platforms, chemical processing equipment pressure vessels and boilers, in heat exchangers.

Offering the industry an improved stainless steel corrosion solution, Duplex 2205 Bolts have good sulfide corrosion resistance, as well as chloride pitting and crevice corrosion superior to 317L. The combination of chromium, molybdenum and nitrogen provides Duplex 2205 bolts with good chloride pitting and crevice corrosion protection, which makes them useful in marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.

Duplex stainless steel UNS S31803 Nuts are available in two phase, 5% to 6% nickel alloy steel, ferritic, 3% molybdenum, austenitic 22% chromium.

2205 duplex grade without requiring higher levels of nickel or molybdenum. This means that it is a low-cost option than most austenitic stainless steel having the same requirements.

Additionally, Duplex 2205 is the most widely used duplex grade on the market. Duplex 2205 alloy is a nitrogen-enhanced duplex stainless steel alloy. The effect of nitrogen is to significantly increase the corrosion resistance of the alloy; especially in the as-welded condition.

Super Duplex UNS S32750 is the most common Super Duplex grade on the market. UNS S32750 is a duplex stainless steel designed for use in corrosive chlorine-containing environments. It has very good localized corrosion and stress corrosion cracking resistance and high mechanical strength. Widely used in oil and gas, hydropower, pressure vessels, pulp and paper, structural parts and chemical tankers.

Duplex2205 washers are dual phase austentic-ferritic duplex fasteners manufactured from alloy containing chromium, nickel alloy and molybdenum with restricted carbon content and minimum PREN35, SAF2205 fasteners have excellent corrosion resistance and high strength.

The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

Due to the alloy’s strong resistance to chemical compositions including acids, bases and neutral solutions, duplex steel uns s31803 nuts would be an ideal addition to these industries.

Stainless Steel Duplex SAF 2205 Hex Bolts are used in machinery and construction and can be used with nuts or threaded holes. Since they can be tightened with a wrench, fully threaded hex bolts are specially designed to work more efficiently. Additionally, 2205 hex bolts are stronger than standard stainless steel, meaning they can be used for jobs that require high workloads and good corrosion resistance.

The higher percentage of chromium in the alloy of duplex stainless steel seamless pipe makes it resistant to oxidation.

Due to the alloy’s very high mechanical strength, dual-phase fastener manufacturers can reduce the weight of their designs by thinning the cross-section of the final product, proving a cost-saving alternative to other grades of stainless steel.

The strength, factorially speaking of an ASTM A790 UNS S31803 Seamless Pipe, is two times higher than that of either of the two stainless steel classes. And the toughness and ductility of the Sa 790 UNS S32205 Welded Pipe are better in comparison to ferritic steels.

The duplex stainless steel grade alloy UNS S32750 Washer is a thin plate, which is typically produced in a disk -shaped, although sometimes square shaped with a hole i.e. sometimes present in the middle.

UNS S31803 Bolted Fasteners are used in marine, agricultural, chemical, construction, shipping, aviation, nuclear and industrial equipment.

Super Duplex Steel Stud Bolt is available in lengths ranging from 2mm to 200mm and has high strength values as well. Super Duplex S32750 is the most common duplex ferritic, austenitic stainless steel grade used for producing stud bolts.

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

La tuberia SA 790 UNS S32205 se utiliza para aplicaciones que funcionan en ambientes ligeramente corrosivos, de presion y temperatura ligeramente alta. Aplicacion de tuberia sin costura Duplex S32205 UNS en sistemas de purificacion de agua y manejo de aguas residuales y alta precision.

Alloy 2507 is highly resistant to carbide-related intergranular corrosion.

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.

An austenitic-ferritic stainless variant with a higher stress corrosion cracking resistance in comparison to regular austenitic 304 and 316 stainless, but with a lower toughness and impact strength.

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.
