EN 1.4596 Stainless Steel vs. 50Cr-50Ni Alloy

EN 1.4596 stainless steel belongs to the iron alloys classification, while 50Cr-50Ni alloy belongs to the otherwise unclassified metals. They have a modest 23% 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 (9, in this case) are not shown.

For each property being compared, the top bar is EN 1.4596 stainless steel and the bottom bar is 50Cr-50Ni alloy.
