AWS E630 vs. 60Cr-40Ni Alloy

AWS E630 belongs to the iron alloys classification, while 60Cr-40Ni alloy belongs to the otherwise unclassified metals. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 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 AWS E630 and the bottom bar is 60Cr-40Ni alloy.
