ASTM A387 Grade 11 Steel vs. Grade 300 Maraging Steel

Both ASTM A387 grade 11 steel and grade 300 maraging steel are iron alloys. They have 67% of their average alloy composition in common. 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 A387 grade 11 steel and the bottom bar is grade 300 maraging steel.
