EN 2.4964 Cobalt vs. AWS ENiCrFe-2

EN 2.4964 cobalt belongs to the cobalt alloys classification, while AWS ENiCrFe-2 belongs to the nickel alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is EN 2.4964 cobalt and the bottom bar is AWS ENiCrFe-2.
