Grade FDSiCr Steel vs. EN 1.4563 Stainless Steel

Both grade FDSiCr steel and EN 1.4563 stainless steel are iron alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is grade FDSiCr steel and the bottom bar is EN 1.4563 stainless steel.
