Nickel 200 vs. AWS E320

Nickel 200 belongs to the nickel alloys classification, while AWS E320 belongs to the iron alloys. They have a modest 35% 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 nickel 200 and the bottom bar is AWS E320.
