SAE-AISI A8 Steel vs. EN 1.4889 Cast Nickel

SAE-AISI A8 steel belongs to the iron alloys classification, while EN 1.4889 cast nickel belongs to the nickel alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI A8 steel and the bottom bar is EN 1.4889 cast nickel.
