Nickel 625 vs. AISI 201LN Stainless Steel
Nickel 625 belongs to the nickel alloys classification, while AISI 201LN stainless steel belongs to the iron alloys. They have a modest 24% 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 (4, in this case) are not shown.
For each property being compared, the top bar is nickel 625 and the bottom bar is AISI 201LN stainless steel.
