EN 1.1118 Cast Steel vs. EN 1.4849 Stainless Steel
Both EN 1.1118 cast steel and EN 1.4849 stainless steel are iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 1.1118 cast steel and the bottom bar is EN 1.4849 stainless steel.
