ASTM A372 Grade D Steel vs. EN 1.4587 Stainless Steel

Both ASTM A372 grade D steel and EN 1.4587 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 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 ASTM A372 grade D steel and the bottom bar is EN 1.4587 stainless steel.
