Grade CW12MW Nickel vs. SAE-AISI D5 Steel

Grade CW12MW nickel belongs to the nickel alloys classification, while SAE-AISI D5 steel belongs to the iron alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 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 grade CW12MW nickel and the bottom bar is SAE-AISI D5 steel.
