ASTM A217 Cast Alloy Steel
ASTM A217 cast steel is an alloy steel formulated for casting.
The properties of ASTM A217 cast steel include nine common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare ASTM A217 cast steel 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.
