Grade VDSiCrV Steel vs. Nickel 890

Grade VDSiCrV steel belongs to the iron alloys classification, while nickel 890 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 (12, in this case) are not shown.

For each property being compared, the top bar is grade VDSiCrV steel and the bottom bar is nickel 890.
