Crack reasons for this are: the heating temperature is too high as a result of quenching or cooling in a hurry, the quality of thermal stress and metal volume changes in the organization of the anti-stress than the breaking strength of steel; the work of the original surface defects (such as surface micro-cracks or scratches) or the internal defect of steel (such as slag, serious non-metallic inclusions, white point, the residual cavity, etc.) formed in the quenching stress concentration; serious Decarburization and carbide surface segregation; parts after quenching Back lack of timely or tempering fire; processes in front of the stress caused by excessive cold red, forging folding, turning deep marks, sharp edges and corners, such as the oil groove.

造成这种裂纹的原因有:由于淬火加热温度过高或冷却太急,热应力和金属质量体积变化时的组织应力大于钢材的抗断裂强度;工作表面的原有缺陷或是钢材内部缺陷(如夹渣、严重的非金属夹杂物、白点、缩孔残余等)在淬火时形成应力集中;严重的表面脱碳和碳化物偏析;零件淬火后回火不足或未及时回火;前面工序造成的冷冲应力过大、锻造折叠、深的车削刀痕、油沟尖锐棱角等。
