SAE-AISI F1 Steel vs. Grade FDSiCr Steel

Both SAE-AISI F1 steel and grade FDSiCr steel are iron alloys. They have a very high 98% of their average alloy composition in common. There are 23 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI F1 steel and the bottom bar is grade FDSiCr steel.
