EN 1.7378 Steel vs. ASTM A182 Grade F92

Both EN 1.7378 steel and ASTM A182 grade F92 are iron alloys. Both are furnished in the normalized and tempered condition. They have a moderately high 91% 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 1.7378 steel and the bottom bar is ASTM A182 grade F92.
