A182 F53 UNS S32750 B16.5 Super Duplex stainless steel flange
What is ASTM A182 F53 Flange?
ASTM A182 F53 is a specification for a type of flange made from a
duplex stainless steel material. The F53 designation refers to the
specific grade of duplex stainless steel used in the flange, which
is also known as UNS S32750 or SAF 2507.
Duplex stainless steels like ASTM A182 F53 offer a combination of
excellent corrosion resistance and high strength, making them
suitable for demanding applications in industries such as oil and
gas, chemical processing, and offshore environments.
The ASTM A182 F53 flange is manufactured according to the
specifications outlined by ASTM International, a globally
recognized standards organization. These flanges are designed to
connect pipes, valves, and other equipment in a piping system,
providing a secure and leak-free connection.
The ASTM A182 F53 flange is commonly used in applications where
resistance to corrosion, pitting, and crevice corrosion is
required, especially in environments with high chloride content. It
offers superior strength and toughness, making it suitable for
high-pressure and high-temperature applications.
Overall, the ASTM A182 F53 flange is a specialized component made
from duplex stainless steel, known for its corrosion resistance and
strength, and it is used in various industries where reliability
and durability are crucial.
