ACI-ASTM CG3M Steel vs. Grade VDC Steel

Both ACI-ASTM CG3M steel and grade VDC steel are iron alloys. They have 66% of their average alloy composition in common. There are 25 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CG3M steel and the bottom bar is grade VDC steel.
