The hot ductility of low carbon low alloy steel and mechanism of surface cracking in relation to the hot ductility have been reviewed in the paper.

The reason was that a mass of oxidation inclusion in steel which induced lowductility, toughness and fatigue intensity, and finally had bad machininged capability.
