ASTM Grade HP Steel vs. ASTM A182 Grade F3VCb

Both ASTM grade HP steel and ASTM A182 grade F3VCb are iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is ASTM grade HP steel and the bottom bar is ASTM A182 grade F3VCb.
