Abstract

СПОСОБ ТЕРМИЧЕСКОЙ ОБРАБОТКИ ИНСТРУМЕНТАЛЬНОЙ СТАЛИ, включающий закалку, первый отпуск при пониженной температуре и окончательный отпуск, отличают виса тем, что, с целью повышени  удар ой в экоств , первый отпуск производ т при температуре начала дисперсионного твердени  IB течение 15-20 мин с последуюшим ускоренным охлаждением, а окончательный отпуск производ т в вакууме при темпе-; ратуре на 5О-8О С ниже прин того.THE METHOD OF THERMAL TOOLING OF TOOL STEEL, including quenching, first tempering at a low temperature and final tempering, is characterized by the fact that, in order to increase the impact on the ecostat, the first tempering is performed at the onset temperature of dispersion hardening IB for 15-20 minutes followed by accelerated cooling, and the final tempering is carried out in vacuum at a temp; The table below is 5O-8O.
