SAE-AISI T4 Steel vs. Nickel 890

SAE-AISI T4 steel belongs to the iron alloys classification, while nickel 890 belongs to the nickel alloys. They have a modest 31% 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 (10, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI T4 steel and the bottom bar is nickel 890.
