ACI-ASTM CF10SMnN Steel vs. AWS ERNiCrMo-3

ACI-ASTM CF10SMnN steel belongs to the iron alloys classification, while AWS ERNiCrMo-3 belongs to the nickel alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CF10SMnN steel and the bottom bar is AWS ERNiCrMo-3.
