EN 1.6554 Steel vs. AWS ERNiFeCr-2

EN 1.6554 steel belongs to the iron alloys classification, while AWS ERNiFeCr-2 belongs to the nickel alloys. They have a modest 21% 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 (7, in this case) are not shown.

For each property being compared, the top bar is EN 1.6554 steel and the bottom bar is AWS ERNiFeCr-2.
