ASTM A369 Grade FPB vs. EN 1.0420 Cast Steel

Both ASTM A369 grade FPB and EN 1.0420 cast steel are iron alloys. Both are furnished in the normalized condition. They have a very high 99% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is ASTM A369 grade FPB and the bottom bar is EN 1.0420 cast steel.
