ASTM A182 F5 Alloy Steel Flange Weldneck Raised Face B16.5



ASTM A182 is an American Society for Testing and Materials standard specifically for forged or rolled alloy and stainless steel flanges, forged fittings, valves, and components for high-temperature service. F11 is a chromium-molybdenum alloy steel. CL2 stands for Class 2, a key classification for F11 material. This designation indicates that the flange undergoes a normalizing and tempering heat treatment, resulting in higher strength and improved mechanical properties than Class 1 (annealing only).
