EN 1.7362 Steel vs. G-CoCr28 Cobalt
EN 1.7362 steel belongs to the iron alloys classification, while G-CoCr28 cobalt belongs to the cobalt alloys. They have a modest 23% 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 1.7362 steel and the bottom bar is G-CoCr28 cobalt.
