EN 2.4642 Nickel vs. S42300 Stainless Steel

EN 2.4642 nickel belongs to the nickel alloys classification, while S42300 stainless steel belongs to the iron alloys. They have a modest 21% 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 (5, in this case) are not shown.

For each property being compared, the top bar is EN 2.4642 nickel and the bottom bar is S42300 stainless steel.
