60Cr-40Ni Alloy vs. ACI-ASTM CF3MN Steel

60Cr-40Ni alloy belongs to the otherwise unclassified metals classification, while ACI-ASTM CF3MN steel belongs to the iron alloys. They have a modest 32% 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 CF3MN steel.
