SAE-AISI H25 Steel vs. EN 1.4889 Cast Nickel

SAE-AISI H25 steel belongs to the iron alloys classification, while EN 1.4889 cast nickel belongs to the nickel alloys. They have a modest 21% 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 (9, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI H25 steel and the bottom bar is EN 1.4889 cast nickel.
