SAE-AISI D2 Steel vs. Nickel 690
SAE-AISI D2 steel belongs to the iron alloys classification, while nickel 690 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 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 nickel 690.
