EN 2.4654 Nickel vs. EN 1.4655 Stainless Steel

EN 2.4654 nickel belongs to the nickel alloys classification, while EN 1.4655 stainless steel belongs to the iron alloys. They have a modest 26% 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 (4, 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 1.4655 stainless steel.
