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.
