EN 1.4558 Stainless Steel vs. N10675 Nickel

EN 1.4558 stainless steel belongs to the iron alloys classification, while N10675 nickel belongs to the nickel alloys. They have a modest 38% 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 1.4558 stainless steel and the bottom bar is N10675 nickel.
