SAE-AISI D5 Steel vs. Nickel 725
SAE-AISI D5 steel belongs to the iron alloys classification, while nickel 725 belongs to the nickel alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 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 D5 steel and the bottom bar is nickel 725.
