Grade CX2MW Nickel vs. EN 1.4104 Stainless Steel

Grade CX2MW nickel belongs to the nickel alloys classification, while EN 1.4104 stainless steel belongs to the iron alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is grade CX2MW nickel and the bottom bar is EN 1.4104 stainless steel.
