EN 2.4654 Nickel vs. EN 1.4749 Stainless Steel

EN 2.4654 nickel belongs to the nickel alloys classification, while EN 1.4749 stainless steel belongs to the iron alloys. They have a modest 21% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is EN 2.4654 nickel and the bottom bar is EN 1.4749 stainless steel.
