AISI 414 Stainless Steel vs. Grade CY40 Nickel

AISI 414 stainless steel belongs to the iron alloys classification, while grade CY40 nickel belongs to the nickel alloys. They have a modest 21% 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 (4, in this case) are not shown.

For each property being compared, the top bar is AISI 414 stainless steel and the bottom bar is grade CY40 nickel.
