EN 1.4490 Stainless Steel vs. N10276 Nickel

EN 1.4490 stainless steel belongs to the iron alloys classification, while N10276 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 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is EN 1.4490 stainless steel and the bottom bar is N10276 nickel.
