EN 2.4951 Nickel vs. AISI 430FSe Stainless Steel

EN 2.4951 nickel belongs to the nickel alloys classification, while AISI 430FSe 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 31 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is EN 2.4951 nickel and the bottom bar is AISI 430FSe stainless steel.
