ASTM A148 Cast Steel vs. Grade FDSiCr Steel

Both ASTM A148 cast steel and grade FDSiCr steel are iron alloys. There are 26 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is ASTM A148 cast steel and the bottom bar is grade FDSiCr steel.
