50Cr-50Ni Alloy vs. AISI 201LN Stainless Steel

50Cr-50Ni alloy belongs to the otherwise unclassified metals classification, while AISI 201LN stainless steel belongs to the iron alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni alloy and the bottom bar is AISI 201LN stainless steel.
