ASTM A216 specification covers carbon steel castings for valves, flanges, fittings, or ther pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
ASTM A216, WCA, WCB, WCC will be selected as per the design and service conditions, mechanical properties, and the high temperature characteristics.
Today, we would like to introduce ASTM A216 WCB carbon steel.
