Cold forging has various advantages compared to other forming processing. Crackingphenomenon was taken place during cold forging of ML25Mn steel. In this study, microstructuralanalyses were made on the cracked regions of the steel. The reason of cracking phenomenonoccurring during cold forging for ML25Mn steel was investigated based on SEM observation indetail. The results have shown that ML25Mn steel presents lower strength and toughness. A largeramount of inclusions which are composed of MnS and complex oxides containing Mg, Al, Mn, Fe,S, Ca and O are found, and the complex inclusion might be brought during the deoxidation and thesolidification in smelting and casting. Non-metallic inclusions result in significant stressconcentration, which cause cracking phenomenon occurring during cold forging of ML25Mn steel
