AISI 201LN Stainless Steel vs. Grade CX2M Nickel

AISI 201LN stainless steel belongs to the iron alloys classification, while grade CX2M nickel belongs to the nickel alloys. They have a modest 23% 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 (6, in this case) are not shown.

For each property being compared, the top bar is AISI 201LN stainless steel and the bottom bar is grade CX2M nickel.
