AWS ERNiFeCr-2 vs. EN 1.3520 Steel

AWS ERNiFeCr-2 belongs to the nickel alloys classification, while EN 1.3520 steel belongs to the iron alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is AWS ERNiFeCr-2 and the bottom bar is EN 1.3520 steel.
