Nickel 22 vs. ACI-ASTM CF16F Steel
Nickel 22 belongs to the nickel alloys classification, while ACI-ASTM CF16F steel belongs to the iron alloys. They have a modest 35% 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 22 and the bottom bar is ACI-ASTM CF16F steel.
