A216 WCC Ball Valve
ASTM A216 WCC ball valves are commonly used in pipelines, as WCC has higher yield strength than A216 WCB. ASTM A216 WCC also has a slightly higher pressure/ temperature rating than A216 WCB. The WCC ball valve may be made by sand casting or precision lost wax investment casting.
More Products: WCC gate valve, WCC globe valve, WCC check valves
Heat treatment process: (Generally all castings need to be annealed or normalized.)
Anneal at 890℃~910℃
Normalization at 870℃~890℃
Simillar Material:
EN 10213 Grade GP280GH, EN 1.0625
