ASTM A321 Carbon Steel vs. EN 1.5682 Steel
Both ASTM A321 carbon steel and EN 1.5682 steel are iron alloys. Both are furnished in the quenched and tempered condition. They have a moderately high 91% of their average alloy composition in common. There are 29 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 A321 carbon steel and the bottom bar is EN 1.5682 steel.
