ACI-ASTM CE30 Steel vs. Grade VDSiCr Steel

Both ACI-ASTM CE30 steel and grade VDSiCr steel are iron alloys. They have 63% of their average alloy composition in common. There are 25 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CE30 steel and the bottom bar is grade VDSiCr steel.
