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.

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.

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.

2205 duplex stainless tubing material, which is why it is referred to as a self-repairing layer.

The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

The corrosion resistance comes from the addition of alloying material, mostly the chromium content. The ASTM A790 Pipes are resistant to pitting corrosion and crevice corrosion. The pipes could also be electric fusion welded.

ASTM A789 / ASME SA789 covers grades of average wall thickness, or, if specified on the order, minimum wall thickness, of stainless steel tubing for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are suscep- tible to embrittlement if used for prolonged periods at elevated temperatures.

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 A479 Super Duplex UNS S32750 F53 Heavy Hex Nuts are kept together by a combination of their threads’ friction (by means of slight elastic distortion), a small widening of the bolt, and solidity of the components to be held together.

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

Duplex 2205 has higher resistance to crevice and erosion corrosion than sus316L austenitic stainless grades.

Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength. Grade S31803 stainless steel was modified several times to form UNS S32205, which was recognized in 1996.

Duplex 2205 round steel contains 22% chromium, 3% molybdenum, and 5-6% nickel. In addition to excellent impact toughness and high strength, it also has high general, local and stress corrosion resistance.

ASTM A790 Duplex 2205 Pipe are precise and used in sensitive applications.

A182 F51 Duplex stainless steel composed of 21% 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.

A182 F53 material displays excellent corrosion resistance.

2205 flange has good sulfide stress corrosion resistance and high strength and good fatigue resistance.

S32760 is a super duplex stainless steel with a ferritic-austenitic microstructure.

ASTM A479 Super Duplex UNS S32750 Fasteners is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades.

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.

Super Duplex S32760 Bar proves to be an excellent replacement for austenitic grades in marine environments. Super Duplex S32760 round bar (ASTM A276/ ASTM A479) exhibits good heat resistance up to 300¡ã.

The mechanical strength, corrosion resistance and low temperature toughness of the ASTM A182 F53 Flanges is higher than that of ordinary duplex stainless steels.

The different face types have their own advantages in piping applications.

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

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. This grade offers higher resistance to corrosion

Compared to conventional stainless steels, duplex steel pipes guarantee higher resistance to pitting and stress corrosion cracking. Meanwhile, our ASTM A 789/A 790 Duplex Steel Pipes and Tubes are available in different sizes, gauges and thicknesses according to customers’ customized requirements.

Duplex 1.4462 round bars also have low thermal expansion and high thermal conductivity as well as high corrosion and erosion fatigue properties compared to austenite. The corrosion resistance of duplex 2205 is almost twice that of other austenitic stainless steels.

The duplex structure results in improved stress-corrosion cracking resistance, compared with the austenitic stainless steels, and improved toughness and ductility, compared with the ferritic stainless steels.

The advantages of duplex steels include: good weldability and machinability, high resistance to corrosion fatigue, resistance to stress corrosion cracking (especially chloride stress corrosion cracking), erosion and high energy absorption.
