Grade CW2M Nickel vs. S24000 Stainless Steel

Grade CW2M nickel belongs to the nickel alloys classification, while S24000 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 25 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is grade CW2M nickel and the bottom bar is S24000 stainless steel.
