Nickel 617 vs. AISI 316Ti Stainless Steel

Nickel 617 belongs to the nickel alloys classification, while AISI 316Ti stainless steel belongs to the iron alloys. They have a modest 34% 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 nickel 617 and the bottom bar is AISI 316Ti stainless steel.
