SAE-AISI A2 Steel vs. Nickel 601

SAE-AISI A2 steel belongs to the iron alloys classification, while nickel 601 belongs to the nickel alloys. They have a modest 20% 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 A2 steel and the bottom bar is nickel 601.
