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.

ASTM A351 CF8M. Austenitic stainless steel classified for Castings, Austenitic, for Pressure-Containing Parts. UNS# J92900 A. As with CF3M, the first character (C) means the alloy is intended for "Corrosion Resistant" service. The second character (F) is the
ASTM A351 CF8M is an upgraded austentic stainless steel alloy of CF8, which contains molybdenum element. The equivalent cast stainless steel alloy is AISI 316 stainless steel. Compared to CF8 stainless steel, The presence of molybdenum in CF8M increases the corrosion resistance and the resistance to pitting by chlorides.
SS316 is defined in ASTM A240 and ASTM A276, it's for plate, sheet, strip or stainless steel bars. Another grade is named as F316, which is from ASTM A182 for Forged parts only. TP316 will be found in ATSTM A376 for pipe only. If you want to buy castings, Pls indicate CF8M as material, otherwise you can adopt SS316.
