N10003 Nickel vs. EN 1.4449 Stainless Steel

N10003 nickel belongs to the nickel alloys classification, while EN 1.4449 stainless steel belongs to the iron 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 N10003 nickel and the bottom bar is EN 1.4449 stainless steel.
