AWS E312 vs. Grade CX2MW Nickel

AWS E312 belongs to the iron alloys classification, while grade CX2MW nickel belongs to the nickel 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 AWS E312 and the bottom bar is grade CX2MW nickel.
