ASTM A216 Grade WCB vs. ASTM A216 Grade WCC
Both ASTM A216 grade WCB and ASTM A216 grade WCC are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.
For each property being compared, the top bar is ASTM A216 grade WCB and the bottom bar is ASTM A216 grade WCC.
