ASTM A372 Grade G Steel vs. EN 1.0591 Cast Steel

Both ASTM A372 grade G steel and EN 1.0591 cast steel are iron alloys. They have a very high 98% 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 A372 grade G steel and the bottom bar is EN 1.0591 cast steel.
