AWS ERNiCrFe-6 vs. ACI-ASTM CE30 Steel

AWS ERNiCrFe-6 belongs to the nickel alloys classification, while ACI-ASTM CE30 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 24 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 AWS ERNiCrFe-6 and the bottom bar is ACI-ASTM CE30 steel.
