What is decarbonized methane?

Decarburized methane refers to the phenomenon that the carbon content in steel decreases.

1. In the process of decarbonization, on the one hand, oxygen diffuses into steel. On the other hand, carbon in steel diffuses outward. From the final result, the decarburization layer can only be formed when the decarburization rate exceeds the oxidation rate.

2. When the oxidation rate is high, obvious decarburization may not occur, that is, iron is oxidized into oxide scale after decarburization layer is produced. Therefore, in the atmosphere with relatively weak oxidation, a deeper decarburization layer can be formed.
