Grade FDSiCr Steel vs. N08221 Nickel

Grade FDSiCr steel belongs to the iron alloys classification, while N08221 nickel belongs to the nickel alloys. They have a modest 29% 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 (13, in this case) are not shown.

For each property being compared, the top bar is grade FDSiCr steel and the bottom bar is N08221 nickel.
