ASTM A182 Grade F12 Class 1 vs. EN 1.8201 Steel

Both ASTM A182 grade F12 class 1 and EN 1.8201 steel are iron alloys. They have a very high 97% 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 F12 class 1 and the bottom bar is EN 1.8201 steel.
