EN 1.4404 Stainless Steel vs. 50Cr-50Ni-Cb Alloy
EN 1.4404 stainless steel belongs to the iron alloys classification, while 50Cr-50Ni-Cb 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 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 EN 1.4404 stainless steel and the bottom bar is 50Cr-50Ni-Cb alloy.
