EN 1.4710 Stainless Steel vs. AWS ERNiCrMo-2
EN 1.4710 stainless steel belongs to the iron alloys classification, while AWS ERNiCrMo-2 belongs to the nickel 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 (9, in this case) are not shown.
For each property being compared, the top bar is EN 1.4710 stainless steel and the bottom bar is AWS ERNiCrMo-2.
