Grade CX2M Nickel vs. EN 1.4568 Stainless Steel

Grade CX2M nickel belongs to the nickel alloys classification, while EN 1.4568 stainless steel belongs to the iron alloys. They have a modest 26% 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 (5, in this case) are not shown.

For each property being compared, the top bar is grade CX2M nickel and the bottom bar is EN 1.4568 stainless steel.
