ASTM A182 Grade F24 vs. Grade VDSiCrV Steel

Both ASTM A182 grade F24 and grade VDSiCrV steel are iron alloys. They have a very high 97% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is ASTM A182 grade F24 and the bottom bar is grade VDSiCrV steel.
