The ASTM A182 F51 steel flanges themselves are available in a variety of sizes and styles to meet the needs of different applications. They can be found in different pressure classes, including 150#, 300#, and 600#, with raised face or flat face options. The flanges can also come in different shapes, such as slip-on, blind, socket weld, and threaded etc.

The duplex stainless steel used in ASTM A182 F51 duplex2205 flanges is a combination of austenitic and ferritic stainless steels. This unique combination of alloys provides the steel with superior strength, especially in high-temperature environments. Additionally, the steel is highly resistant to corrosion, pitting, and crevice corrosion, making it a perfect choice for harsh and corrosive environments.
