The first hot cracking is called segregation crack, because the liquid film formation and solidification process of segregation of alloying elements

316l NO.1 stainless steel pipe

Solidification process, the front surface of the solidified melt zone is rich in alloying elements and residual elements. Thus, in the end of the solidification process there will be a small amount of residual liquid distribution in the solidified microstructure between to separate them. Solidification and cooling stages of the resulting shrinkage strain and shrinkage strain an additional expansion will have a surface crack and internal crack. Even in the subsequent hot forming process, the internal solidification cracking can not be eliminated, if the material is subjected to greater tension load, where segregation of alloying elements will fracture. If these areas further in the subsequent processing is cut off, these parts may become the starting point of quenching cracks occur or lead to material splitting.
