Grade CW6M Nickel vs. EN 1.4470 Stainless Steel

Grade CW6M nickel belongs to the nickel alloys classification, while EN 1.4470 stainless steel belongs to the iron alloys. They have a modest 30% 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 (7, in this case) are not shown.

For each property being compared, the top bar is grade CW6M nickel and the bottom bar is EN 1.4470 stainless steel.
