EN 1.7710 Steel vs. N08135 Stainless Steel

Both EN 1.7710 steel and N08135 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 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is EN 1.7710 steel and the bottom bar is N08135 stainless steel.
