AWS BNi-3 vs. EN 1.4805 Stainless Steel

AWS BNi-3 belongs to the nickel alloys classification, while EN 1.4805 stainless steel belongs to the iron alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is AWS BNi-3 and the bottom bar is EN 1.4805 stainless steel.
