ACI-ASTM CE30 Steel vs. AWS ERNiCr-3

ACI-ASTM CE30 steel belongs to the iron alloys classification, while AWS ERNiCr-3 belongs to the nickel alloys. They have a modest 32% 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 CE30 steel and the bottom bar is AWS ERNiCr-3.
