Description
ASTM A182 F11 WN RF Flange, Chrome Molybdenum Alloy Forged Weld Neck Raised Face Flange
Brief Introduction

ASTM A182 F11 WN RF Flange is a high-performance chrome-molybdenum alloy forged flange, strictly manufactured in accordance with ASTM A182 and ASME B16.5 standards. F11 (UNS K11547) is a classic Cr-Mo alloy steel grade, featuring excellent high-temperature strength, creep resistance, hydrogen embrittlement resistance, and superior weldability. As a Weld Neck (WN) flange with Raised Face (RF), it is specially designed for high-temperature, high-pressure, and hydrogen-containing industrial piping systems, providing strong structural integrity and reliable sealing performance, widely applied in power plants, petrochemical, refinery, and other critical fields where stable operation under harsh working conditions is required.
