EN 1.4477 Stainless Steel vs. AWS ERNiCr-3

EN 1.4477 stainless steel belongs to the iron alloys classification, while AWS ERNiCr-3 belongs to the nickel alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is EN 1.4477 stainless steel and the bottom bar is AWS ERNiCr-3.
