60Cr-40Ni Alloy vs. ACI-ASTM CF8M Steel

60Cr-40Ni alloy belongs to the otherwise unclassified metals classification, while ACI-ASTM CF8M steel belongs to the iron alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is 60Cr-40Ni alloy and the bottom bar is ACI-ASTM CF8M steel.
