ASTM A732 Grade 13Q Cast Steel

ASTM A732 grade 13Q is a type of ASTM A732 cast steel. Cited properties are appropriate for the quenched and tempered condition. The graph bars on the material properties cards below compare ASTM A732 grade 13Q to: cast alloy 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.
