Nickel 601 vs. AISI 420 Stainless Steel
Nickel 601 belongs to the nickel alloys classification, while AISI 420 stainless steel belongs to the iron alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is nickel 601 and the bottom bar is AISI 420 stainless steel.
