Heat treatment and ion nitriding modes influence on strength properties of the high-speed steels

The paper presents results of studying mechanical properties of the R6M5, R6M5K5, R9M4K8 and R8M3K6S high-speed steels subjected to heat treatment in four modes. Specific impact strength, strength and yield limits in tension, compression, bending and torsion were determined. For each grade of the high-speed steel, the samples hardness was identified, where highest values of the strength characteristics were ensured. Mechanical tests were carried out on samples made of high-speed steels subjected to ion nitriding. Recommendations are provided in selecting the optimal combination of the heat treatment and nitriding modes for certain high-speed steels.
