AWS ERNiFeCr-2 vs. SAE-AISI D3 Steel

AWS ERNiFeCr-2 belongs to the nickel alloys classification, while SAE-AISI D3 steel belongs to the iron alloys. They have a modest 31% 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 (5, in this case) are not shown.

For each property being compared, the top bar is AWS ERNiFeCr-2 and the bottom bar is SAE-AISI D3 steel.
