ASTM A387 Grade 2 Steel vs. EN 1.4852 Stainless Steel
Both ASTM A387 grade 2 steel and EN 1.4852 stainless steel are iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is ASTM A387 grade 2 steel and the bottom bar is EN 1.4852 stainless steel.
