EN 1.4482 Stainless Steel vs. Grade CY40 Nickel

EN 1.4482 stainless steel belongs to the iron alloys classification, while grade CY40 nickel belongs to the nickel alloys. They have a modest 25% 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 EN 1.4482 stainless steel and the bottom bar is grade CY40 nickel.
