ASTM A209 Steel vs. Grade FDSiCr Steel

Both ASTM A209 steel and grade FDSiCr steel are iron alloys. 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 ASTM A209 steel and the bottom bar is grade FDSiCr steel.
