The most significant difference is that A351 has tensile property, inspection, and quality requirements not found in A743. A351 references A703 which in turn sets out the testing & analysis methods and requirements. A743 references A781, a general specification for casting used in non-pressurized applications.

316/316L STAINLESS VALVES. Valves are manufactured in ASTM A182 316/316L forgings and ASTM A351 CF8/CF3 castings. Trim components can also be in UNS S31600 and AISI-SAE 316/316L. Welded end valves can be in 316 but 316L is often preferred due to the lower carbon content which avoids inter granular corrosion in the as-welded state thereby

Stainless Steel CG8M. CG8M is one 19 Cr/11 Ni with Mo stainless steel grade which listed in ASTM A351 and ASTM A743 and ASTM A744 standard. Casting UNS number is J93000. CG8M is much better than CF8M because it has 3%-4% content of Molybdenum but CF8M only has 2%-3% Mo. WWW.CASTINGQUALITY.COM.
CF8M ist in ASMT A351, ASMT A743 und ASTM A744 definiert, die nur für Gusszwecke ist. SS316 ist in ASTM A240 und ASTM A276 definiert, es ist für Platten, Bleche, Streifen oder Edelstahlstäbe. Grade F316, die von ASTM A182 für Schmiedeteile nur ist. TP316 wird in ATSTM A376 für Rohr nur gefunden werden.
CAST STEEL VALVES First, let's clarify the difference between cast vs. forged valve, even if it may seem obvious: cast valves feature a cast body, forged valves have a forged body. That's it! The difference relates to the valve body material construction technique, i.e. steel forging or casting. Let's now review the key cast valve body materials.

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.

After 304, 316 is the most common stainless steel on the market. It is an austenitic grade with the addition of 2-3% molybdenum which further improves corrosion resistance. It is often referred to as a marine grade stainless steel because of its effective resistance to chloride corrosion in comparison to other stainless steel grades.
