AISI 440A Stainless Steel vs. Nickel 600

AISI 440A stainless steel belongs to the iron alloys classification, while nickel 600 belongs to the nickel alloys. They have a modest 24% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 AISI 440A stainless steel and the bottom bar is nickel 600.
