Duplex stainless / UNS S32205 is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.
One of the main attractions of duplex stainless steel is cost – due to the materials increased yield strength it is often possible to reduce the thickness of material making it much cheaper than a comparative austenitic stainless steel grade.
Corrosion resistance much better than that of Type 316
Greater tensile and yield strength
Good ductility and toughness though not as good as austenitic grades
Good stress corrosion cracking resistance (SSC)
Opportunity for purchases to reduce their material costs without compromising on quality
The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel. This feature enables designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is particularly suitable for the temperature range of -50°F / +600°F.
Where stainless steel pipes are used in sewage treatment plants:
[1] There are severe corrosive liquid media (bad water quality).
[2] Import and export of sewage pumps.
[3] Exhibition of environmental areas with strong observation.
[4] Where acidic water content is high
If you need to change the direction of the pipeline, we usually use different angle elbows made of stainless steel to change the transportation direction of the pipeline.

A hybrid austenite/ferrite microstructure (50/50) with greater strength than ferritic and austenitic acid steel with equal corrosion resistance properties is the Duplex Stainless / UNS S32205.
One of the big attractive features of duplex stainless steel is the expense of producing it much cheaper than the comparatively austenitic grade of stainless steel because of its improved yield strength.
Our Duplex Steel pipes are available as Duplex Steel s32205 tee, Duplex Steel Reducer, Duplex Steel Cross s32205, and Duplex Steel s32205 end caps, and are available as Duplex Steel S32205 steel cushion. Duplex steel pipe accessories are also available. Duplex Steel is a high corrosion resistance to austenitic-ferritic stainless steel. Toughness and the strength of the duct are higher than other grades of Duplex steels. These types of steel can have a corrosion resistance like any form of austenitic steel. The lower content of nickel and molybdenum present in them will lead to lower costs. In contrast to austenitic steels, the production force also increases. These WNR 1.4462 Butt Weld pipe attachments can be used in organic fuel and more plants. Our UNS S32205 Cross complies with foreign production and reliability requirements. Our highly developed facilities allow us to create excellent products at low prices.
Since the duplex derives a mixed microstructure from the same austenite and ferrite component, the Ferritic alloy offers stress cracking strength and austenitic alloy provides fast development and roost resistance. These tubular fittings function in the conditions of acid reduction and oxidation as well as in the construction of gas sweetening materials. The higher the nitrogen content, the greater the corrosion resistance. Due to its specific characteristics and properties, 2205 pipe fittings are highly needed. These products are produced and distributed in a range of shapes and sizes according to customer requirements.
The pipes are supplied to different industries, including reservoirs, boiler manufacturing, and desalination plants. In the manufacturing of tube fittings and duplex stainless-steel tubing, the lower percentage of alloy elements is cheaper. These tube fittings are manufactured according to national and international specifications and are well checked and inspected using the best raw material quality. A full line of pipes and fittings such as UNS S32205 45 deg is given by manufacturers.
