60Cr-40Ni Alloy vs. S21904 Stainless Steel
60Cr-40Ni alloy belongs to the otherwise unclassified metals classification, while S21904 stainless steel belongs to the iron alloys. They have a modest 28% 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 (14, in this case) are not shown.
For each property being compared, the top bar is 60Cr-40Ni alloy and the bottom bar is S21904 stainless steel.
