Grade N12MV Nickel vs. AWS E385

Grade N12MV nickel belongs to the nickel alloys classification, while AWS E385 belongs to the iron alloys. They have a modest 36% 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 (10, in this case) are not shown.

For each property being compared, the top bar is grade N12MV nickel and the bottom bar is AWS E385.
