AWS E209 vs. Grade CX2M Nickel

AWS E209 belongs to the iron alloys classification, while grade CX2M nickel belongs to the nickel alloys. They have a modest 37% 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 (8, in this case) are not shown.

For each property being compared, the top bar is AWS E209 and the bottom bar is grade CX2M nickel.
