Zusammenfassung:Mechanical component having a surface at least one part of which has been surface hardened by induction heating. A cross section of the mechanical component through the surface exhibits a hardness Hsurface at the surface, and remains substantially equal through a first region, a hardness Hcore at the non-hardened core of the mechanical component and remains substantially equal through a third region and a transition, second region spanning between the first and third regions. The hardness profile in the first region has an average hardness Y1, and the hardness profile in the third region has an average hardness Y3. If a line is drawn on the hardness profile in the second region between the points (formula) and (formula), where 0
