SAE-AISI M36 Steel vs. Grade CW12MW Nickel

SAE-AISI M36 steel belongs to the iron alloys classification, while grade CW12MW nickel belongs to the nickel alloys. They have a modest 21% 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 (9, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI M36 steel and the bottom bar is grade CW12MW nickel.
