EN 1.4889 Cast Nickel vs. SAE-AISI 4820 Steel

EN 1.4889 cast nickel belongs to the nickel alloys classification, while SAE-AISI 4820 steel belongs to the iron alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.4889 cast nickel and the bottom bar is SAE-AISI 4820 steel.
