EN 2.4665 Nickel vs. SAE-AISI M6 Steel

EN 2.4665 nickel belongs to the nickel alloys classification, while SAE-AISI M6 steel belongs to the iron alloys. They have a modest 30% 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 (10, in this case) are not shown.

For each property being compared, the top bar is EN 2.4665 nickel and the bottom bar is SAE-AISI M6 steel.
