ASTM A182 F11 is a forged alloy steel pipe flanges material grade intended for high-temperature service.
Chromoly F11 (Cr-Mo) is part of the Chromoly family of low-alloy steel – an alloy of chromium and molybdenum. Chromoly F11 Flanges are strong, weldable, and cost-effective, which makes them popular in applications across Marine, Navy, and Petrochemical Industries
ASTM A182 covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves
Grade F11 also called 1 1/4 CRMO, often referred to as “one and a quarter chrome
F11 chrome subsets are Class 1, 2, and 3. Each class has a higher yield strength, tensile strength, and Brinell hardness value than the one before it.
Chrome moly flanges offer a level of chromium not quite reaching the levels of common stainless steels like 304 and 316, but more so than typical A105. In comparison to carbon steel, the higher levels of chromium provide a superior hardness and overall mechanical integrity, whereas the higher molybdenum content is useful in resisting oxidation and corrosion.
Weld Neck or Welding Neck (WN) flange includes a long tapered hub that aid in reinforcement and provide temperature / pressure resistance. Bored to match the inside diameter of the mating pipe or fitting, these flanges are directly welded to the end of the pipe.
ASTM A182 F11 Flange is one of the most popular grade used in oil&gas refinery applications.
