AISI 301LN Stainless Steel vs. Nickel 725

AISI 301LN stainless steel belongs to the iron alloys classification, while nickel 725 belongs to the nickel alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 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 AISI 301LN stainless steel and the bottom bar is nickel 725.
