Can decarburization occur in low carbon and low alloy wire rods? Why?
Therefore, low carbon alloy steel may also be decarburization, the normal production process and good surface quality, there will be no high carbon steel such as all decarburization layer, but local is also possible!
We have exported to 10B21, because the technical agreement indicated in the low carbon steel does not exist decarburization, cause me a quality objection, because of the presence of surface defects, leading to the existence of local decarburization slight surface defects.
In addition, when there is surface defect in the continuous casting billet, the decarburization layer of the slab is deformed because of the existence of the defect, so that a small amount of decarburization layer can be preserved in a small amount.However, in the physical and chemical examination, the low carbon steel is not tested by the decarburization layer, and the decarburization occurring in the normal production process is also a small amount of decarburization.
According to the truth, because of containing carbon steel, oxidation must occur in the heating process, and alloy steel, some alloy increases the decarburization tendency of carbon steel, low carbon steel so will produce decarburization, especially in high temperature and long time stay in the process.
