ACI-ASTM CF10SMnN Steel vs. Type 4 Magnetic Alloy

ACI-ASTM CF10SMnN steel belongs to the iron alloys classification, while Type 4 magnetic alloy belongs to the nickel alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CF10SMnN steel and the bottom bar is Type 4 magnetic alloy.
