SAE-AISI D2 Steel vs. EN 2.4668 Nickel

SAE-AISI D2 steel belongs to the iron alloys classification, while EN 2.4668 nickel belongs to the nickel alloys. They have a modest 32% 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 (3, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI D2 steel and the bottom bar is EN 2.4668 nickel.
