EN 2.4951 Nickel vs. S45503 Stainless Steel

EN 2.4951 nickel belongs to the nickel alloys classification, while S45503 stainless steel belongs to the iron alloys. They have a modest 24% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is EN 2.4951 nickel and the bottom bar is S45503 stainless steel.
