EN 1.8509 Steel vs. N08028 Stainless Steel

Both EN 1.8509 steel and N08028 stainless 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 (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.8509 steel and the bottom bar is N08028 stainless steel.
