What is ASTM A182 F55 Flanges?
ASTM A182 F55 Super Duplex Flange is an alloy with high concentrations of chromium, molybdenum, and nitrogen that provides excellent strength and corrosion resistance. ASTM A182 F55 Super Duplex Flanges are available in a variety of sizes and configurations and can be manufactured in raised face, flat face, or ring joint styles. ASTM A182 F55 flanges are often used in applications with high levels of stress and corrosion, such as the oil and gas industry or marine applications.
For example, the UNS S32760 F55 Weld Neck Raised Face Flange (WNRF), is designed to connect multiple pipes together. ASTM A182 Gr F55 WN Flanges are also known for their excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, which makes them ideal for high pressure and high temperature applications.
ASME SA 182 F55 Material Applications
- Valves, Pumps and Heat Exchangers
- Chemical Processing
- Petrochemical
- Marine Engineering
Gr F55 VS F53
S32750 (also known as SAF 2507 or F53) contains a higher amount of chromium, molybdenum, and nitrogen than S32760 (also known as Zeron 100 or F55). This makes S32750 more corrosion-resistant and suitable for use in seawater and chloride-containing environments. On the other hand, S32760 has a higher amount of copper, which improves its resistance to acid corrosion.
