EN 1.3520 Steel vs. S35045 Stainless Steel

Both EN 1.3520 steel and S35045 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 24 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is EN 1.3520 steel and the bottom bar is S35045 stainless steel.
