ASTM A414 Steel vs. Grade 200 Maraging Steel

Both ASTM A414 steel and grade 200 maraging steel are iron alloys. There are 24 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is ASTM A414 steel and the bottom bar is grade 200 maraging steel.
