Nickel 690 vs. AISI 301LN Stainless Steel
Nickel 690 belongs to the nickel alloys classification, while AISI 301LN 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 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is nickel 690 and the bottom bar is AISI 301LN stainless steel.
