Nickel 689 vs. ACI-ASTM CC50 Steel
Nickel 689 belongs to the nickel alloys classification, while ACI-ASTM CC50 steel belongs to the iron alloys. They have a modest 24% 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 (13, in this case) are not shown.
For each property being compared, the top bar is nickel 689 and the bottom bar is ACI-ASTM CC50 steel.
