ASTM A217 Cast Steel vs. Grade 300 Maraging Steel

Both ASTM A217 cast steel and grade 300 maraging steel are iron alloys. There are 23 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is ASTM A217 cast steel and the bottom bar is grade 300 maraging steel.
