50Cr-50Ni-Cb Alloy vs. ACI-ASTM CE3MN Steel

50Cr-50Ni-Cb alloy belongs to the otherwise unclassified metals classification, while ACI-ASTM CE3MN steel belongs to the iron alloys. They have a modest 33% 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 50Cr-50Ni-Cb alloy and the bottom bar is ACI-ASTM CE3MN steel.
