Grade CW2M Nickel vs. AWS E309Mo

Grade CW2M nickel belongs to the nickel alloys classification, while AWS E309Mo belongs to the iron alloys. They have a modest 34% 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 grade CW2M nickel and the bottom bar is AWS E309Mo.
