AWS ERNi-1 vs. EN 1.4807 Stainless Steel

AWS ERNi-1 belongs to the nickel alloys classification, while EN 1.4807 stainless steel belongs to the iron alloys. They have a modest 36% 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 ERNi-1 and the bottom bar is EN 1.4807 stainless steel.
