EN 1.4594 Stainless Steel vs. N06230 Nickel

EN 1.4594 stainless steel belongs to the iron alloys classification, while N06230 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 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is EN 1.4594 stainless steel and the bottom bar is N06230 nickel.
