EN 1.4415 Stainless Steel vs. Grade CX2M Nickel

EN 1.4415 stainless steel belongs to the iron alloys classification, while grade CX2M nickel belongs to the nickel alloys. They have a modest 21% 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 EN 1.4415 stainless steel and the bottom bar is grade CX2M nickel.
