Nickel 600 vs. ACI-ASTM CG8M Steel

Nickel 600 belongs to the nickel alloys classification, while ACI-ASTM CG8M 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 (7, in this case) are not shown.

For each property being compared, the top bar is nickel 600 and the bottom bar is ACI-ASTM CG8M steel.
