S32205 elbow

ASME B16.9 Duplex Stainless Steel Seamless Fittings range from sch5 to sch160 and XXS. Welded fittings with wall thicknesses up to 50 mm. Because the duplex material is strong and resistant to acid and chloride ion corrosion, fittings such as ASTM A815 UNS S32205 Long Radius Elbow are used in seawater, marine and highly corrosive applications such as the oil, oil and gas and offshore oil drilling industries.

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. The yield strength of duplex stainless steel products is higher than that of austenitic stainless steel products, so users can buy duplex pipes and duplex pipe fittings with relatively lower thickness.

In fact, the above properties of 317L fittings are considered to be much better than traditionally used stainless grades such as 304, 304L, 316 and 316L. The alloys used for stainless steel 317L are known to provide better resistance than 316L, especially in highly corrosive environments, which may contain chemicals such as sulfur-containing media, chlorides and other halides.

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.

Duplex Steel Buttweld Fittings demonstrate better localized corrosion resistance in comparison to both grade 316L and 317L. Hence these duplex steel fittings are used in applications involving several key industrial fields such as chemical plants, seawater pump, seawater desalination plant, and so on.

Werkstoff No 1.4462 Duplex Steel Pipe Fittings have a high resistance to intergranular corrosion, especially in chloride and sulphide containing environments. Usually, a regular steels grade would be susceptible to getting degraded in these conditions, unlike Duplex Stainless Steel Fittings, which exhibit very high resistance to stress related corrosion cracking.

These duplex accessories are supplied in various industries such as brewing tanks, boiler construction and desalination plants. We stock a full line of 2205 Duplex Fittings to meet your piping requirements.

The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by durable ferrite phases. In the toughened state, 2205 contains approximately 40-half ferrite. Duplex steels derive identical austenitic and ferritic fractions of a mixed microstructure. Ferritic alloys offer strength against stress cracking, while austenitic alloys offer ease of manufacture and rust resistance. These tubular fittings work under acid reducing and oxidizing conditions and in building materials in gas desulfurization plants.

The higher the nitrogen content, the better the corrosion resistance. 2205 fittings are highly demanded for the unique characteristics and performance they exhibit in their application. These products are manufactured and delivered in various shapes and sizes according to customer requirements. These pipes are transported to various industries including storage tanks, boiler production and desalination plants. The percentage of alloying elements used in the manufacture of fittings and duplex stainless steel pipes is lower at lower cost.

These fittings are produced from the highest quality raw materials and are well tested and inspected according to national and international standards. Manufacturers offer a full range of pipes and fittings such as UNS S32205 45 degrees. Elbow, Duplex UNS S31803 Reducer, Duplex S31803 Cap, Duplex S31803 Butt Weld Fitting, 2205 Duplex 90 Degree Elbow, Duplex S32205 Butt Weld Fitting, Duplex S32205 Fitting.

253 MA Pipe Fittings are austenitic stainless steel nickel-chromium alloyed fitting adding with unusual earth metals and nitrogen. The fittings have superior oxidation resistance up to 1150 degree C and general corrosion resistance. It offers outstanding creep strength along with superior resistance to erosion and sulfidation at elevated temperature. Through the tight control of micro-alloy addition these demonstrate superior heat resistance properties. The fittings have superior ductility and maintain its good formability. The presence of nitrogen and chromium content possess resistance to pitting and stress corrosion cracking.

2205 is the most widely used duplex (ferritic/austenitic) stainless steel pipe fittings. It is used due to its excellent corrosion resistance and high strength. Duplex S31803 fittings offer a better guarantee of corrosion resistance, but most duplex S31803 currently produced also complies with duplex S31803. 1.4462 belongs to the DUPLEX steel series. This steel has higher corrosion resistance than eg austenitic 1.4404. Therefore, the tensile yield point is about 150% higher.
