EN 1.4470 Stainless Steel vs. N10624 Nickel

EN 1.4470 stainless steel belongs to the iron alloys classification, while N10624 nickel belongs to the nickel alloys. They have a modest 24% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 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 1.4470 stainless steel and the bottom bar is N10624 nickel.
