EN 1.0411 Steel vs. R30556 Alloy
Both EN 1.0411 steel and R30556 alloy are iron alloys. They have a modest 30% 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 (4, in this case) are not shown.
For each property being compared, the top bar is EN 1.0411 steel and the bottom bar is R30556 alloy.
