ASTM F15 Fe-Ni-Co vs. 50Cr-50Ni Alloy
ASTM F15 Fe-Ni-Co belongs to the iron alloys classification, while 50Cr-50Ni alloy belongs to the otherwise unclassified metals. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is ASTM F15 Fe-Ni-Co and the bottom bar is 50Cr-50Ni alloy.
