EN 1.4587 Stainless Steel vs. EN 1.3570 Steel

Both EN 1.4587 stainless steel and EN 1.3570 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 25 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 1.4587 stainless steel and the bottom bar is EN 1.3570 steel.
