EN 1.3975 Stainless Steel vs. EN 2.4669 Nickel

EN 1.3975 stainless steel belongs to the iron alloys classification, while EN 2.4669 nickel belongs to the nickel alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is EN 1.3975 stainless steel and the bottom bar is EN 2.4669 nickel.
