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

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.

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.

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.

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).

The pressure-temperature ratings for ASTM A182 F53 flanges are the same as that for other duplex stainless steels.

Duplex is often found in desalination and pressure vessel equipment located in port cities.

Austenitic has a low strength and a low resistance to stress corrosion cracking, while ferritic also has a low strength, poor weldability and poor low temperature toughness. Producing a chemical composition that combines austenitic and ferritic results in a metal that has a higher strength, good weldability, good toughness and resistance to stress corrosion cracking.

This provides the flanges with high corrosion resistance and higher mechanical properties. Please contact us for your orders of F53 flanges.

Duplex 2205 was tested under reverse bending stress at room temperature compared to SS316. The results show that Duplex 2205 has approximately twice the fatigue limit/yield strength.

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

Duplex steel flange also offers Good weldability and workability, High energy absorption and Low thermal expansion.

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

Light gauges of 2507 material can often be used to achieve the same design strength of thicker nickel alloys. Duplex 2507 plate is suitable for applications requiring excellent strength and corrosion resistance. It contains 25% chromium, 4% molybdenum and 7% nickel.

El uso de tuberias sin costura ASTM A790 UNS S32205 (sin costura y soldadas) es adecuado para aplicaciones generales, pero la solucion principal que brindan es el agrietamiento por corrosion relacionado con la tension.

The UNS S32750 standard of Pipe Fittings consists of 25% chromium, 4% molybdenum, and 7% nickel. The UNS S32750 Pipe Fittings have a 50-50 microstructure of ferritic and austenitic steel grades with improved strength.

Duplex 2205 is a nitrogen-enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel).

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.

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

The raised face allows for the flange to have more bolt holes and connection surface while the welded neck grips the pipe in place. The applications are oil and gas, petroleum, petrochemical and other industrial applications.

Stainless steel round bar is a cylindrical stainless steel product, which is widely used in auto parts, aviation, aerospace hardware tools, chemical industry and other industries. Stainless steel WNR 1.4301 wire is known for its amazing tensile strength and fabric power and is available in a variety of sizes according to customer requirements. They are the product of the best materials and primary strategies that conform to the established norms of the industry. In our assortment we have round rods with special type of ends to ensure short and tight fittings in pipes.

Offshore marine engineering plants need compenents that meet their rugged demands, components that have mammoth strenght but are light weight.

ASTM A182 UNS S32750 Flanges is the most common super duplex grade that has an enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types.

2205 fasteners are widely used in applications requiring good corrosion resistance and strength. Has excellent corrosion resistance; much higher than other grades. It eliminates localized corrosion types such as intergranular corrosion, pitting corrosion and crevice corrosion. Duplex 2205 bolts are ideal for environments containing chlorides and hydrogen sulfide for oil and gas extraction from sour wells, refineries, and chloride-contaminated process solutions.

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.
