We developed, mastered and introduced the technology of smelting, dispersion, compacting, deformation processing, heat and adjustment treatment of new powder high-alloy tool steels of the following grades: R3M3F4-MP, R7M- 7F7K11-MP, R14M3F5K11-MP, 140Kh5M4F4-MP, 110Kh8M2FSС-MP, Kh14MF9-MP, Kh18MF3S-MP, 8Kh8MF3- MP. The quality of sectional metal products of the new powder steels meets the requirements of TU DSS 005-13 and technical protocols. 2 Ref., 2 Tabl., 3 Fig.
