EN 1.8901 Steel vs. N08535 Stainless Steel

Both EN 1.8901 steel and N08535 stainless steel are iron alloys. They have a modest 39% 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 1.8901 steel and the bottom bar is N08535 stainless steel.
