SAE-AISI M3 Class 1 Steel vs. Nickel 333

SAE-AISI M3 class 1 steel belongs to the iron alloys classification, while nickel 333 belongs to the nickel alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI M3 class 1 steel and the bottom bar is nickel 333.
