ASTM A182 F5 Alloy Steel Flange for High-Temp Pressure Systems
ASTM A182 F5 Alloy Steel Flange for High-Temp Pressure Systems
Brief Introduction
ASTM A182 F5 flange is a high-performance chromium-molybdenum (Cr-Mo) alloy steel flange, strictly compliant with ASTM A182 / ASME SA182 standard. It is made of F5 alloy steel (UNS K11562), featuring excellent high-temperature strength, good weldability, and strong corrosion resistance to high-temperature media. As a key pipeline connection component, it is mainly used for connecting pipelines in medium-high temperature and medium-high pressure industrial systems, suitable for long-term service under harsh working conditions up to 593℃, ensuring stable and leak-free pipeline operation.
