AWS E383 vs. AWS ERNi-1
AWS E383 belongs to the iron alloys classification, while AWS ERNi-1 belongs to the nickel alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 E383 and the bottom bar is AWS ERNi-1.
