EN 1.1170 Steel vs. N08135 Stainless Steel
Both EN 1.1170 steel and N08135 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 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 1.1170 steel and the bottom bar is N08135 stainless steel.
