SAE-AISI M6 Steel vs. Nickel 689

SAE-AISI M6 steel belongs to the iron alloys classification, while nickel 689 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 19 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI M6 steel and the bottom bar is nickel 689.
