SAE-AISI H42 Steel vs. EN 2.4889 Nickel

SAE-AISI H42 steel belongs to the iron alloys classification, while EN 2.4889 nickel belongs to the nickel alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI H42 steel and the bottom bar is EN 2.4889 nickel.
