EN 2.4889 Nickel vs. SAE-AISI O6 Steel

EN 2.4889 nickel belongs to the nickel alloys classification, while SAE-AISI O6 steel belongs to the iron alloys. They have a modest 25% 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 EN 2.4889 nickel and the bottom bar is SAE-AISI O6 steel.
