EN 1.3543 Stainless Steel vs. Grade CW6M Nickel

EN 1.3543 stainless steel belongs to the iron alloys classification, while grade CW6M nickel belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is EN 1.3543 stainless steel and the bottom bar is grade CW6M nickel.
