Unlike CF8M and CF3M of ASTM A351, CF8C grade has option for stabilization treatment due to Nb present which forms carbides, between 870 and 900 °C after solution annealing in austenite matrix. This prevents depletion of chromium around grain boundary and prevents sensitization of steel. However, this stabilization treatment …

A forged valve body is produced by forging and machining solid steel. The key specifications for cast steel valves body materials are ASTM A216 (WCA, WCB, WCC), ASTM A352 LCB/LCC (low-temperature), and ASTM A351 CF8/CF8M. ASTM A105, A350 and A182 cover body materials for small size (or high pressure) forged valves.
