Nickel 617 vs. ACI-ASTM CD4MCu Steel

Nickel 617 belongs to the nickel alloys classification, while ACI-ASTM CD4MCu 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 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is nickel 617 and the bottom bar is ACI-ASTM CD4MCu steel.
