EN 1.0314 Steel vs. N08020 Stainless Steel

Both EN 1.0314 steel and N08020 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 (4, in this case) are not shown.

For each property being compared, the top bar is EN 1.0314 steel and the bottom bar is N08020 stainless steel.
