EN 1.4587 Stainless Steel vs. EN 1.0558 Cast Steel

Both EN 1.4587 stainless steel and EN 1.0558 cast 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 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.4587 stainless steel and the bottom bar is EN 1.0558 cast steel.
