EN 1.0070 Steel vs. EN 1.4874 Stainless Steel

Both EN 1.0070 steel and EN 1.4874 stainless steel are iron alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 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 1.0070 steel and the bottom bar is EN 1.4874 stainless steel.
