Grade CX2MW Nickel vs. AWS E309L

Grade CX2MW nickel belongs to the nickel alloys classification, while AWS E309L belongs to the iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is grade CX2MW nickel and the bottom bar is AWS E309L.
