EN 1.0031 Steel vs. ASTM Grade HE Steel

Both EN 1.0031 steel and ASTM grade HE steel are iron alloys. They have 60% of their average alloy composition in common. There are 30 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 EN 1.0031 steel and the bottom bar is ASTM grade HE steel.
