EN 1.8201 Steel vs. ASTM A182 Grade F911

Both EN 1.8201 steel and ASTM A182 grade F911 are iron alloys. Both are furnished in the normalized and tempered condition. They have a moderately high 92% of their average alloy composition in common. There are 32 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 EN 1.8201 steel and the bottom bar is ASTM A182 grade F911.
