| Summary: | In the article there are examined the peculiarities of the structure and characteristics of cast and deformed high-speed steels R6M5 and R6M5K5. It is established, that there is practically no difference in hardness and heat stability, at the same time cast steels because of the structure specificity are inferior to the deformed ones in impact elasticity, considerably exceeding them in endurance. On the basis of industrial tests it is shown that at correct nomenclature choice for embedding there are being created the backgrounds for secure work of cast instrument, resistance of which can be even higher as compared to the traditional instrument due to higher endurance of cast-steel |
