| description | A steel tie rod end includes a shaft portion and first and second fitting portions. A minimum area portion having a small radially cross-sectional area is provided for the shaft portion, and 90% or above of a steel structure of the minimum area portion is formed of martensite or tempered martensite. The surface hardness of the minimum area portion and the average hardness of the radial cross section of the minimum area portion are 600 Hv or below, and the average hardness of the radial cross section of the first fitting portion and the average hardness of the radial cross section of the second fitting portion are 300 Hv or below. A method of manufacturing a steel tie rod end includes a quenching process of heating only a prospective shaft portion by high frequency to an austenitizing temperature and then rapidly cooling the prospective shaft portion by water or cooling medium. |
