EN 1.4951 Stainless Steel vs. N10629 Nickel

EN 1.4951 stainless steel belongs to the iron alloys classification, while N10629 nickel belongs to the nickel alloys. They have a modest 26% 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 (9, in this case) are not shown.

For each property being compared, the top bar is EN 1.4951 stainless steel and the bottom bar is N10629 nickel.
