FORGED COMPONENT, METHOD FOR MANUFACTURING THE SAME, AND CONNECTING ROD |
摘要 |
A forged component having a chemical composition including, by mass %, C: 0.30 to 0.45%, Si: 0.05 to 0.35%, Mn: 0.50 to 0.90%, P: 0.030 to 0.070%, S: 0.040 to 0.070%, Cr: 0.01 to 0.50%, Al: 0.001 to 0.050%, V: 0.25 to 0.35%, Ca: 0 to 0.0100%, N: 0.0150% or less, and the balance being Fe and unavoidable impurities, and satisfying formula 1. Metal structure is a ferrite pearlite structure, and a ferrite area ratio is 30% or more. Vickers hardness is in the range of 320 to 380 HV. 0.2% yield strength is 800 MPa or more. A Charpy V-notch impact value is in the range of 7 to 15 J/cm2. |

1: A forged component having a chemical composition comprising, by mass %, C: 0.30 to 0.45%, Si: 0.05 to 0.35%, Mn: 0.50 to 0.90%, P: 0.030 to 0.070%, S: 0.040 to 0.070%, Cr: 0.01 to 0.50%, Al: 0.001 to 0.050%, V: 0.25 to 0.35%, Ca: 0 to 0.0100%, N: 0.0150% or less, and the balance being Fe and unavoidable impurities, and satisfying the following formula 1:
[C]−4×[S]+[V]−25×[Ca]<0.44 Formula 1:(wherein [X] means a value of the content (mass %) of an element X), wherein
metal structure is a ferrite pearlite structure, and a ferrite area ratio is 30% or more; Vickers hardness is in the range of 320 to 380 HV; 0.2% yield strength is 800 MPa or more; and a Charpy V-notch impact value is in the range of 7 to 15 J/cm2. |
