Are You Looking for 2205 Duplex Stainless Steel Blind and Slip on Flanges in Custom size Call Now or mail us your drawing!

The Duplex Flanges are made from a stainless steel alloy that has both austenitic and ferritic microstructure. The 2205 Flanges are known for their high strength, and they can also withstand corrosion resistance better than 300 series stainless steel. This means that the Duplex Stainless Steel Flanges can better avoid stress corrosion cracking, which is commonly seen in the 316 and 317 grade stainless steel. However, the toughness and impact strength of the 2205 Duplex Stainless Steel Flanges is much lower compared to the 300 series stainless steel.
The ASTM A182 S32205 Pipe Flange has become quite popular in the last few years due to its exceptional chemical as well as mechanical properties. Compared to the stainless steel grades, the Duplex 2205 Blind Raised Face Flange has good usability and their cost difference has also become minimal due to increase in availability.
The ASTM A182 Gr F51 Uns S31803 Flange has a superior weight to strength ratio, and it possesses decent mechanical toughness. The ASTM A182 Gr F60 Flange however comes with difficult formability and they are great for fixed service simple flange connections. However, the SAF 2205 Slip On Flanges material has high workability and thus forming them into a round and complex structure is quite easy.
The DIN 1.4462 Forged Flange has high ductility and they have a long service life without much maintenance. This is why the ASTM A182 S32205 pipe flange is used for a wide range of applications across several industries like chemical, fertilizers, oil and gas, etc. An important reason why Asme Sa182 S32205 Welding Neck Flange is considered, because of its good resistance to stress corrosion cracking.
The ASTM A182 F51 Duplex Steel SWRF Flange can be effectively used in sea water and power generation equipment. The Saf 2205 Slip On Flanges come with a smooth surface and they show good performance upto the temperature of 600 degrees F. Flanges made with the ASTM A182 Uns S31803 Material also show excellent flow characteristics.
The Alloy 2205 threaded flanges are used in pipes that come with external threads- they can be attached easily without any welding. The duplex steel Lap Joint Flanges is used primarily in pipelines that require frequent dismantling to undergo routine inspections or maintenance.
The Duplex 2205 Flanges can be customized according to the shape, size, and dimensional requirements of the client. The surface finish of the Duplex Steel UNS S31803 F51 can also be changed as per the application needs. Clients should invest in high quality and dimensionally accurate Duplex Steel Gr. F60 S32205 products for optimal performance.
