ACI-ASTM CA6N Steel vs. Grade FDC Steel

Both ACI-ASTM CA6N steel and grade FDC steel are iron alloys. They have 81% 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 CA6N steel and the bottom bar is grade FDC steel.
