| Abstract: | Conclusions A beneficial effect of boriding may be expected only on a tool which is made of steel having a hardening temperature not above 1080°C and the technical specifications of which do not have a ground shape, e.g., dies made of steel 9KhS, taps and reamers made of steel U12, and also forged tools made of steel Kh12.For high-speed steels it is apparently only possible to subject those tool to boriding for which red hardness is not obligatory (e.g., certain components of special bearings) of fusion of the cutting edge is acceptable (e.g., certain types of cutters). For the rest of the objects made of high-speed steels boriding is unsuitable.All-Union Scientific-Research Tool Institute (VNII).
