ASTM A182 Grade F10 vs. G-CoCr28 Cobalt
ASTM A182 grade F10 belongs to the iron alloys classification, while G-CoCr28 cobalt belongs to the cobalt alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is ASTM A182 grade F10 and the bottom bar is G-CoCr28 cobalt.
