Grade CX2MW Nickel vs. ACI-ASTM CF10SMnN Steel

Grade CX2MW nickel belongs to the nickel alloys classification, while ACI-ASTM CF10SMnN steel belongs to the iron alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 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 grade CX2MW nickel and the bottom bar is ACI-ASTM CF10SMnN steel.
