Nickel 825 vs. SAE-AISI L3 Steel
Nickel 825 belongs to the nickel alloys classification, while SAE-AISI L3 steel belongs to the iron alloys. They have a modest 32% 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 nickel 825 and the bottom bar is SAE-AISI L3 steel.
