ASTM Grade HP Steel vs. SAE-AISI 1086 Steel
Both ASTM grade HP steel and SAE-AISI 1086 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 SAE-AISI 1086 steel.
