Nickel 30 vs. ACI-ASTM CA28MWV Steel

Nickel 30 belongs to the nickel alloys classification, while ACI-ASTM CA28MWV steel belongs to the iron alloys. They have a modest 30% 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 (5, in this case) are not shown.

For each property being compared, the top bar is nickel 30 and the bottom bar is ACI-ASTM CA28MWV steel.
