This iron carbide is extremely diverse from your Solid iron the rest of the disc is composed of. It is extremely tough, incredibly brittle, and does not soak up heat well. Right after cementite is formed, the integrity with the disc is compromised. Even if the disc floor is machined, the cementite within the disc will not likely wear or take in heat at the exact same fee as the Solid iron surrounding it, resulting in the uneven thickness and uneven heating properties of your disc to return.
