EN 2.4851 Nickel vs. S40910 Stainless Steel

EN 2.4851 nickel belongs to the nickel alloys classification, while S40910 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 31 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 2.4851 nickel and the bottom bar is S40910 stainless steel.
