ASTM A210 Steel vs. Grey Cast Iron

Both ASTM A210 steel and grey cast iron are iron alloys. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is ASTM A210 steel and the bottom bar is grey cast iron.
