EN 1.4959 Stainless Steel vs. N10665 Nickel

EN 1.4959 stainless steel belongs to the iron alloys classification, while N10665 nickel belongs to the nickel alloys. They have a modest 34% 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 (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.4959 stainless steel and the bottom bar is N10665 nickel.
