EN 2.4669 Nickel vs. AISI 304L Stainless Steel

EN 2.4669 nickel belongs to the nickel alloys classification, while AISI 304L stainless steel belongs to the iron alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is EN 2.4669 nickel and the bottom bar is AISI 304L stainless steel.
