AWS E80C-Ni3 vs. Chromium 33

AWS E80C-Ni3 belongs to the iron alloys classification, while chromium 33 belongs to the otherwise unclassified metals. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 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 AWS E80C-Ni3 and the bottom bar is chromium 33.
