Grade 350 Maraging Steel vs. ACI-ASTM CC50 Steel

Both grade 350 maraging steel and ACI-ASTM CC50 steel are iron alloys. They have 65% of their average alloy composition in common. There are 20 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is grade 350 maraging steel and the bottom bar is ACI-ASTM CC50 steel.
