Nickel 80A vs. ACI-ASTM CH20 Steel

Nickel 80A belongs to the nickel alloys classification, while ACI-ASTM CH20 steel belongs to the iron alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is nickel 80A and the bottom bar is ACI-ASTM CH20 steel.
