Grade CX2M Nickel vs. S32506 Stainless Steel

Grade CX2M nickel belongs to the nickel alloys classification, while S32506 stainless steel belongs to the iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is grade CX2M nickel and the bottom bar is S32506 stainless steel.
