EN 1.0314 Steel vs. ASTM Grade HP Steel

Both EN 1.0314 steel and ASTM grade HP steel are iron alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is EN 1.0314 steel and the bottom bar is ASTM grade HP steel.
