| titleOfInvention | Non-tempered steel for soft nitriding, soft nitriding component, and method for manufacturing soft nitriding component |
| abstract | Provided is a non-tempered steel for soft nitriding, in which the nitrocarburized part after nitrocarburizing is excellent in bending fatigue strength and bending straightening. Non-tempered steel for soft nitriding according to the present invention is mass%, C: 0.20 to 0.40%, Si: 0.10 to 0.80%, Mn: more than 1.20% to 1.60% , S: 0.100% or less, Al: 0.005-0.030%, Ti: 0.001-0.020%, and N: 0.008-0.025%, with the balance being Fe and It consists of impurities and has a chemical composition that satisfies formulas (1) and (2). In the microstructure of steel, the total area ratio of pro-eutectoid ferrite and pearlite is 95% or more, the pro-eutectoid ferrite fraction is 55% or more, and the average crystal grain size of pro-eutectoid ferrite is 10 to 90 μm. 0.94 ≦ C + 0.43Mn + 2.19Cr ≦ 1.02 (1) C−0.006Si + 0.076Mn + 0.46Cr ≦ 0.50 (2) The element symbols in the formulas (1) and (2) indicate the corresponding element The content (mass%) of is substituted. |
