ASTM A182 Grade F23 vs. EN 1.7375 Steel

Both ASTM A182 grade F23 and EN 1.7375 steel are iron alloys. Both are furnished in the normalized and tempered condition. They have a very high 98% 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 ASTM A182 grade F23 and the bottom bar is EN 1.7375 steel.
