Grade FDSiCr Steel vs. N08028 Stainless Steel

Both grade FDSiCr steel and N08028 stainless steel are iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is grade FDSiCr steel and the bottom bar is N08028 stainless steel.
