Ferrite vs. SAE-AISI 4150 Steel
Ferrite and SAE-AISI 4150 steel belong to fundamentally different material chemistries. Ferrite is a ceramic material, while SAE-AISI 4150 steel is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (25, in this case) are not shown.
For each property being compared, the top bar is ferrite and the bottom bar is SAE-AISI 4150 steel.
