S28200 Stainless Steel vs. Grade CX2MW Nickel

S28200 stainless steel belongs to the iron alloys classification, while grade CX2MW nickel belongs to the nickel alloys. They have a modest 24% 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 (9, in this case) are not shown.

For each property being compared, the top bar is S28200 stainless steel and the bottom bar is grade CX2MW nickel.
