Super Duplex 2507 nut for chemical process petrochemical and seawater equipment

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.

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.

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 .

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

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.

Duplex Steel S32205 bar stock is a ferritic, duplex, austenitic 3% molybdenum, 22% chromium and 5% – 6% nickel alloy stainless steel.

Application fields of duplex stainless steel:
¡¤ Pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry).
¡¤ Oil and gas pipelines, heat exchanger fittings.
¡¤ Sewage treatment system.

Duplex stainless steel pipes and fittings are generally less expensive because of the lower proportions of alloying elements used in the manufacture of duplex stainless steels. Compared to austenitic stainless steels, duplex stainless steels have higher yield strengths, so users can buy duplex pipes and duplex pipe fittings in relatively lower thicknesses.

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

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

ASTM A815 specification covers two general classes, WP and CR, of wrought ferritic, ferritic/austenitic, and martensitic stainless steel fittings of seamless and welded construction. Class WP fittings are subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and WP-WU. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products.
Teel Industry has grown in the past few decades and there are a variety of products available in the market. ASTM A815 UNS S32750 Pipe Fittings are one of those products and are available in various sizes, shapes, and dimensions. ASTM A815 UNS S32760 Pipe Fittings are designed to be resistant to corrosion and are said to have perfect weldability. These Super Duplex S32750 Buttweld Fittings are resistant to erosion corrosion and fatigue. They have a mixed microstructure of 50% austenitic and 50% ferrite.

There are SA 182 F53 S32750 Blind Flanges, socket weld flanges and weld neck flanges in this range of material. The different flanges are used in different applications set ups.

Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.

The presence of ferrite in the duplex 2205 welded pipe is what provides for an enhanced performance of this stainless steel grade in caustic media containing environments.

The chemistry of this steel ensures better performance with higher mechanical properties in comparison to austenitic stainless steel pipes.

Zeron 100 Threaded Rod are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.SA 182 F55 is a forging grade of Alloy 32760 or UNS 32760 which is highly resistant to crevice corrosion and pitting alloy for variety of corrsives. It is 22% chromium duplex stainless steel.

The flanges shall not be used at temperatures over 600¡ãF [315¡ãC] since it may be subject to embrittlement after service at moderately elevated temperatures.

The high oxidation resistance property of Grade 2205 is marred by its embrittlement above 300¡ãC. This embrittlement can be modified by a full solution annealing treatment. This grade performs well at temperatures below 300¡ãC.

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.

Grade UNS S31803 is termed as a duplex class due to its mixed Austenitic-ferritic microstructure. Duplex stainless steel alloys have an equal proportion of both austenite and ferrite, which is why Duplex Steel Fittings exhibit properties prominent to both classes.

Another advantage of grade 304 stainless steel bar over grade 303 is that it is slightly harder and has better corrosion resistance. Because of this, grade 304 stainless steel bar is used in large quantities in the manufacture of fasteners and fixtures such as nuts, bolts, washers, clips, fittings and clamps. Products made from grade 304 stainless steel in the fastener industry are often referred to as “A2”.
