ASTM Grade HC Steel vs. ASTM Grade HP Steel

Both ASTM grade HC steel and ASTM grade HP steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 66% of their average alloy composition in common. There are 29 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 ASTM grade HC steel and the bottom bar is ASTM grade HP steel.
