| Description
| - Induction hardening is one of perspective methods of increasing fatigue strength of rolling stock axles, which has already been used on a different steel grade in Japan for many years. The main reasons why the induction hardening technology should be further developed are: Fatigue strength increased by about 58% (418 / 264) compared to the standard EA4T steel grade and about 74% compared with EN 13261 standard, which cannot be achieved by any other technologies. This implies usability of application of the induction hardening technology on highly loaded powered axles made of EA4T steel grade.Price affordable technology, the costs of which is comparable to application of a molybdenum layer, The difference being that induction hardening provides a comprehensive protection of the entire axle from the wheel seat through the axle body to the opposite wheel seat. The coefficient of notch sensitivity, determined on the reduced specimens with 10 mm diameter, met the requirements of the standard for EA4T grade steel and was not significantly increased. Small disadvantage is reduction of the coefficient of notch strength and generally also of plasticity, measured as elongation at break, in the sub-surface induction hardened layers, which are outside of the requirement range of the European standard.
