EN 2.4964 Cobalt vs. AISI 310S Stainless Steel

EN 2.4964 cobalt belongs to the cobalt alloys classification, while AISI 310S stainless steel belongs to the iron alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 EN 2.4964 cobalt and the bottom bar is AISI 310S stainless steel.
