Grade CX2M Nickel vs. AISI 205 Stainless Steel

Grade CX2M nickel belongs to the nickel alloys classification, while AISI 205 stainless steel belongs to the iron alloys. They have a modest 20% 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 CX2M nickel and the bottom bar is AISI 205 stainless steel.
