EN 1.4854 Stainless Steel vs. EN 1.1131 Cast Steel

Both EN 1.4854 stainless steel and EN 1.1131 cast 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 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.4854 stainless steel and the bottom bar is EN 1.1131 cast steel.
