AWS E308LMo vs. Grade CX2M Nickel

AWS E308LMo belongs to the iron alloys classification, while grade CX2M nickel belongs to the nickel alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 E308LMo and the bottom bar is grade CX2M nickel.
