ASTM Grade HP Steel vs. EN 1.0214 Steel

Both ASTM grade HP steel and EN 1.0214 steel are iron alloys. They have a modest 37% 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 ASTM grade HP steel and the bottom bar is EN 1.0214 steel.
