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.

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 .

Duplex 2205 is a nitrogen enhanced duplex stainless steelthat was developed to combat common corrosion problems encountered with the 300 series stainless steels. ¡°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. In the annealed condition, 2205 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.

ASTM A240 UNS S32750 plate is suitable for high tension and high corrosion environments.

Duplex stainless steel fasteners are made from alloys with high chromium content and low to moderate nickel content.

2205 duplex stainless steel is more than double that of ordinary austenitic stainless steel. This characteristic allows designers to reduce weight when designing products, giving this alloy a price advantage over 316,317L.

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 ASTM A182 F51 flanges refer to standard or non-standard flanges manufactured in accordance with ASTM A182 Grade F51, which is designated with UNS number S31803.

Duplex 2205 fasteners have high toughness and hardness while also possessing high levels of tensile strength, all as a result of the chromium present in them. However, it can be concluded that dual phase steel fasteners are undeniable; neither deformed nor damaged. This anomaly is much less likely to happen. 2205 Duplex Fasteners consume delicate structures made from ferritic and austenitic stainless steels that are considered part of an alloy, and the end result provides excellent mechanical properties in duplex fasteners.

The S31803 fastener series demonstrates the properties of ferritic and austenitic stainless steels. These fasteners exhibit excellent resistance to crevice corrosion, stress corrosion cracking and pitting corrosion in harsh environments. In addition, these are excellent in resistance to chloride and sulfide stress corrosion environments.

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

UNS31803 has been supplemented by S32205 (F60) which dual conforms to S31803 but has a higher minimum N, MO, NI and Cr which guarantees a better corrosion resistance.

The temperature in heat exchange is usually increased because they work according to the principle of heat transfer. While A789 tubing can hold its own at high temperatures, it is not recommended for use in temperatures above 600F. Duplex 2205 Tube may become brittle and rot at temperatures above 600F.

La tuberia soldada ASTM A790 UNS S32205 se fabrica para obtener una resistencia adicional. Los tubos soldados se laminan en caliente, mientras que los tubos sin costura se estiran en frio.Ambos pueden reforzarse aun mas mediante el trabajo en frio, pero hasta cierto punto.

Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking (including sulfide stress corrosion cracking), pitting, crevice corrosion and high strength when compared with other stainless alloys.

Super Duplex Steel 1.4410 Flanges are having low alloying costs as compared to the similar ferritic and austenitic grade along with resistant to corrosion in the chloride-containing atmosphere because of well-enhanced yielding and tensile strength.

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy.

Supplied in the annealed condition, it has a yield strength of 80ksi (550Mpa), which is higher than most austenitic and duplex grades.

2507 nuts are highly resistant to carbide-related intergranular corrosion due to their low carbon content (0.020% in weight).

Thread friction between the nut and bolt creates a strong, steady and even force holding the componenuts together. The most commonly used ASTM A182 UNS S32205 fastener nuts are regular hex nuts. At the same time, duplex stainless steel fasteners are strong and corrosion resistanut, combining the healthy properties of ferrite and austenite. The material also has a 90ksi minimum tensile strength and a 65ksi minimum yield strength. 2205 duplex stainless steel bolts have an elongation of 25% and a hardness of 217HBW.

The ASTM A182 UNS S32750 Slip On Flanges are good to use with seamless pipes.

UNS S31803 Bolt is a threaded fastener with external threads. Generally, like screws, alloy S31803 bolts tend to use a variety of head designs.

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

Super Duplex UNS S32750 is the most common super duplex grade in the market. UNS S32750 is a duplex stainless steel especially designed for service in aggressive chloride-containing environments.

Alloy 2205 UNS S32305/S31803 is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed Duplex Stainless Steel Pipe with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

Stainless steel grade UNS S31803 is highly resistant to intergranular corrosion due to its low carbon content, which prevents carbide precipitation at grain boundaries.

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.

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.

We are manufacturers of ASTM A182 Duplex UNS S32750 / S32760 Flanges show enhanced pitting corrosion resistance in saline environments, brackish waters, bleaching operations, and selected food processing applications.

Cold drawn and cold rolled is the primarily prepare for 2205 Duplex Stainless Steel Pipe. Due to the material characteristic of high quality and hardness, duplex steel is more difficult to process than austenitic steel. It is very easy to damage, particularly for small thickness and large diameter pipes, it incorporates a long and hard-working methods.

Duplex 2205 fasteners are made from cost-effective, long-lasting and corrosion-resistant steel. The grade of steel used to make fasteners can be ferritic, austenitic or dual phase steel. Duplex materials have the strength qualities of ferritic steels and the corrosion-resistant qualities of austenitic steels.

Compared to 317L stainless steel, duplex steel has excellent resistance to chloride pitting and crevice corrosion. The alloy has excellent corrosion resistance to seawater and most concentrations of sulfuric acid. In addition, it is resistant to sulfide stress corrosion cracking (sour gas environments)
