AISI 420 Stainless Steel vs. Nickel 600
AISI 420 stainless steel belongs to the iron alloys classification, while nickel 600 belongs to the nickel alloys. They have a modest 22% 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 (6, in this case) are not shown.
For each property being compared, the top bar is AISI 420 stainless steel and the bottom bar is nickel 600.
