EN 1.4449 Stainless Steel vs. N10003 Nickel

EN 1.4449 stainless steel belongs to the iron alloys classification, while N10003 nickel belongs to the nickel alloys. They have a modest 25% 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 (4, in this case) are not shown.

For each property being compared, the top bar is EN 1.4449 stainless steel and the bottom bar is N10003 nickel.
