ASTM A182 Super Duplex Steel F53 / UNS 32750 Flanges are flanges made from a specific grade of super duplex stainless steel known as F53 or UNS 32750. Super duplex stainless steels are a subgroup of duplex stainless steels, offering superior strength and exceptional corrosion resistance. The chemical composition of F53/UNS 32750 typically includes around 25% chromium (Cr), 7% to 7.5% nickel (Ni), 3.5% to 5% molybdenum (Mo), 0.24% to 0.32% nitrogen (N), and small amounts of other elements like tungsten (W) and copper (Cu).

The key feature of ASTM A182 Super Duplex Steel F53 / UNS 32750 Flanges is their outstanding corrosion resistance, particularly in aggressive environments. The high chromium, molybdenum, and nitrogen content provide exceptional resistance to general corrosion, pitting, and crevice corrosion. These flanges are well-suited for use in harsh conditions, such as seawater, brackish water, and chloride-containing solutions, making them ideal for marine and offshore applications.

In addition to their excellent corrosion resistance, F53/UNS 32750 flanges offer higher strength compared to standard duplex stainless steels. They exhibit good ductility and toughness, enabling them to withstand high-pressure and high-temperature applications in various industrial settings.

Super Duplex Steel UNS S32750 Flanges

ASTM A182 Duplex Steel F53 Flanges do not require heat treatment after manufacturing, as they are typically supplied in the solution-annealed condition. The as-supplied properties are usually sufficient for most applications, allowing for ease of fabrication and installation.
