Целью изобретени вл етс повышение износостойкости и ударной в зкости при термоциклировании в интервале температур 20-350°С.The aim of the invention is to increase wear resistance and toughness during thermal cycling in the temperature range 20-350 ° C.
Плавки предлагаемой и известной сталей провод т в индукционной печи . Термическа обработка: закалка 900°С, отпуск 350°С. Количество от- . пусков 10, продолжительность отпуска 15 мин. Испытани на износостойкость провод т в шаровой мельнице диаметром 0,8 м, заполненной щебе- нем фракции 5-10 мм в течение 120 ч на образцах 10 х 10 х 25 мм. Износостойкость определ ют как обратную величину потери веса 5 образцовMelting of the proposed and known steels is carried out in an induction furnace. Thermal treatment: hardening 900 ° С, tempering 350 ° С. Number from- starts 10, the duration of the vacation 15 minutes. The wear resistance tests were carried out in a ball mill with a diameter of 0.8 m, filled with rubble of 5–10 mm for 120 hours on samples of 10 x 10 x 25 mm. Wear resistance is defined as the reciprocal of the weight loss of 5 samples.
каждой партии. Ударную в зкость определ ют по известной методике. Результаты испытании приведены в таблице .each batch. Impact strength is determined by a known technique. The test results are shown in the table.
Предлагаема сталь обладает более высокой износостойкостью и ударной в зкостью по сравнению с известной сталью.The proposed steel has a higher wear resistance and toughness compared with the known steel.
