Grade VDC Steel vs. N08120 Nickel

Grade VDC steel belongs to the iron alloys classification, while N08120 nickel belongs to the nickel alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is grade VDC steel and the bottom bar is N08120 nickel.
