EN 1.4031 Stainless Steel vs. N06250 Nickel

EN 1.4031 stainless steel belongs to the iron alloys classification, while N06250 nickel 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 26 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.4031 stainless steel and the bottom bar is N06250 nickel.
