Остальное Предлагаемую сталь выплавл ют в индукционной печи емкостьр 12О кГ по обычной технологии. и азот ввод т в ковш в различных количествах. Готовую сталь разливают фракционно на пробы , из которых изготовл ют стандартные образцы дл механических испытаний. .Образцы подвергают термообработке по режиму: нормализаци при 1050 С с охлаждением на воздухе; закалка при 1ООО-105О С в масле; отпуск при 600-65Ос на воздухе.Remaining The proposed steel is smelted in an induction furnace with a capacity of 12O kg according to the usual technology. and nitrogen is introduced into the ladle in varying amounts. The finished steel is poured fractionally into the samples from which standard samples for mechanical testing are made. The samples are heat treated according to the following conditions: normalization at 1050 ° C with air cooling; quenching at 1OOO-105O С in oil; Vacation at 600-65 ° C in the air.
Результаты испытаний образцов приведены в таблице.The test results of the samples are shown in the table.
