Abstract The effect of Ce on inclusions and impact toughness of 2Cr13 stainless steel were studied by SEM and electron spectroscopy. Thermodynamic calculation was used to analyze the formation of RE inclusions in 2Cr13 stainless steel. The result shows that Al2O3 and MnS can be entirely replaced by Ce2O2S and CeS. Fracture is changed from cleavage to ductile fracture by adding Ce to the 2Cr13 stainless steel, and the spherical rare earth oxysulfide inclusions-Ce2O2S in the dimple are the main factors. The transverse impact value of 2Cr13 stainless steel has been improved obviously by rare earth. The transverse impact value of RE-2Cr13 is increased 55.46% at the temperature of -40��, comparing with 0RE-2Cr13.
