Grade M35-2 Nickel vs. S32050 Stainless Steel

Grade M35-2 nickel belongs to the nickel alloys classification, while S32050 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 29 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 grade M35-2 nickel and the bottom bar is S32050 stainless steel.
