AISI 201LN Stainless Steel vs. AWS BCo-1

AISI 201LN stainless steel belongs to the iron alloys classification, while AWS BCo-1 belongs to the cobalt alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 18 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is AISI 201LN stainless steel and the bottom bar is AWS BCo-1.
