EN 2.4654 Nickel vs. AISI 384 Stainless Steel

EN 2.4654 nickel belongs to the nickel alloys classification, while AISI 384 stainless steel belongs to the iron alloys. They have a modest 36% 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 2.4654 nickel and the bottom bar is AISI 384 stainless steel.
