ASTM A387 Grade 11 Steel vs. EN 1.4854 Stainless Steel
Both ASTM A387 grade 11 steel and EN 1.4854 stainless steel are iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 32 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
For each property being compared, the top bar is ASTM A387 grade 11 steel and the bottom bar is EN 1.4854 stainless steel.
