50Cr-50Ni Alloy vs. S32906 Stainless Steel

50Cr-50Ni alloy belongs to the otherwise unclassified metals classification, while S32906 stainless steel belongs to the iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni alloy and the bottom bar is S32906 stainless steel.
