AWS E219 vs. Grade CW12MW Nickel

AWS E219 belongs to the iron alloys classification, while grade CW12MW nickel belongs to the nickel alloys. They have a modest 30% 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 E219 and the bottom bar is grade CW12MW nickel.
