R30003 Cobalt vs. ASTM A182 Grade F92

R30003 cobalt belongs to the cobalt alloys classification, while ASTM A182 grade F92 belongs to the iron alloys. They have a modest 26% 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 R30003 cobalt and the bottom bar is ASTM A182 grade F92.
