ASTM Grade HC Steel vs. 50Cr-50Ni-Cb Alloy

ASTM grade HC steel belongs to the iron alloys classification, while 50Cr-50Ni-Cb alloy belongs to the otherwise unclassified metals. They have a modest 31% 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 (10, in this case) are not shown.

For each property being compared, the top bar is ASTM grade HC steel and the bottom bar is 50Cr-50Ni-Cb alloy.
