Nickel 825 vs. SAE-AISI M62 Steel

Nickel 825 belongs to the nickel alloys classification, while SAE-AISI M62 steel belongs to the iron alloys. They have a modest 37% 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 (12, in this case) are not shown.

For each property being compared, the top bar is nickel 825 and the bottom bar is SAE-AISI M62 steel.
