EN 2.4642 Nickel vs. ACI-ASTM CA6N Steel

EN 2.4642 nickel belongs to the nickel alloys classification, while ACI-ASTM CA6N steel belongs to the iron alloys. They have a modest 28% 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 EN 2.4642 nickel and the bottom bar is ACI-ASTM CA6N steel.
