EN 2.4964 Cobalt vs. S32050 Stainless Steel

EN 2.4964 cobalt belongs to the cobalt alloys classification, while S32050 stainless steel belongs to the iron alloys. They have a modest 32% 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 S32050 stainless steel.
