50Cr-50Ni-Cb Alloy vs. AWS E16-8-2

50Cr-50Ni-Cb alloy belongs to the otherwise unclassified metals classification, while AWS E16-8-2 belongs to the iron alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 18 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 50Cr-50Ni-Cb alloy and the bottom bar is AWS E16-8-2.
