Grade VDSiCrV Steel vs. ASTM Grade HC Steel

Both grade VDSiCrV steel and ASTM grade HC steel are iron alloys. They have 70% of their average alloy composition in common. There are 24 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is grade VDSiCrV steel and the bottom bar is ASTM grade HC steel.
