ASTM A216 Grade WCC Cast Steel

ASTM A216 grade WCC is a type of ASTM A216 cast steel. Cited properties are appropriate for the annealed condition. The graph bars on the material properties cards below compare ASTM A216 grade WCC to: cast carbon steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
