Grade M35-2 Nickel vs. S35140 Stainless Steel

Grade M35-2 nickel belongs to the nickel alloys classification, while S35140 stainless steel belongs to the iron alloys. They have a modest 29% 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 (5, in this case) are not shown.

For each property being compared, the top bar is grade M35-2 nickel and the bottom bar is S35140 stainless steel.
