EN 1.3549 Stainless Steel vs. EN 2.4654 Nickel

EN 1.3549 stainless steel belongs to the iron alloys classification, while EN 2.4654 nickel belongs to the nickel alloys. They have a modest 21% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is EN 1.3549 stainless steel and the bottom bar is EN 2.4654 nickel.
