Grade CY40 Nickel vs. S21603 Stainless Steel

Grade CY40 nickel belongs to the nickel alloys classification, while S21603 stainless steel belongs to the iron alloys. They have a modest 28% 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 (10, in this case) are not shown.

For each property being compared, the top bar is grade CY40 nickel and the bottom bar is S21603 stainless steel.
