AISI 316L Stainless Steel vs. Nickel 689

AISI 316L stainless steel belongs to the iron alloys classification, while nickel 689 belongs to the nickel alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 AISI 316L stainless steel and the bottom bar is nickel 689.
