EN 2.4815 Cast Nickel vs. SAE-AISI 8620 Steel

EN 2.4815 cast nickel belongs to the nickel alloys classification, while SAE-AISI 8620 steel belongs to the iron alloys. They have a modest 22% 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 (2, in this case) are not shown.

For each property being compared, the top bar is EN 2.4815 cast nickel and the bottom bar is SAE-AISI 8620 steel.
