EN 2.4663 Nickel vs. EN 1.4421 Stainless Steel

EN 2.4663 nickel belongs to the nickel alloys classification, while EN 1.4421 stainless steel belongs to the iron alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 2.4663 nickel and the bottom bar is EN 1.4421 stainless steel.
