50Cr-50Ni-Cb Alloy vs. AWS E630

50Cr-50Ni-Cb alloy belongs to the otherwise unclassified metals classification, while AWS E630 belongs to the iron alloys. They have a modest 22% 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 E630.
