S15500 Stainless Steel vs. 60Cr-40Ni Alloy

S15500 stainless steel belongs to the iron alloys classification, while 60Cr-40Ni alloy belongs to the otherwise unclassified metals. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is S15500 stainless steel and the bottom bar is 60Cr-40Ni alloy.
