ASTM A217 Cast Steel vs. Austenitic Nodular Cast Iron
Both ASTM A217 cast steel and austenitic nodular cast iron are iron alloys. There are 24 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is ASTM A217 cast steel and the bottom bar is austenitic nodular cast iron.
