AISI 384 Stainless Steel vs. Nickel 693

AISI 384 stainless steel belongs to the iron alloys classification, while nickel 693 belongs to the nickel alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is AISI 384 stainless steel and the bottom bar is nickel 693.
