ACI-ASTM CA6NM Steel vs. Nickel 693

ACI-ASTM CA6NM steel belongs to the iron alloys classification, while nickel 693 belongs to the nickel alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CA6NM steel and the bottom bar is nickel 693.
