которые после закалки и отпуска подвергаютс  жидкому цианированию, а отпуск провод т при температуре цианировани .which, after quenching and tempering, undergo liquid cyanidation, and tempering is carried out at the cyanidation temperature.

Легированные стали могут при известных услови х содержать дополнительно .0,1% бора и 0,3% вольфрама по отдельности или вместе.Alloyed steels may, under certain conditions, additionally contain .0.1% boron and 0.3% tungsten separately or together.

Подвергаемые азотированию полотна пил сначала закаливают в масле при 900- 950°С и отпускают при 540-570°С. После предпочтительно полировани  производ т жидкое цианирование в течение 10-25 мин. В заключение полотна пил прав т раст жением и рихтуют. Твердость изготовленных согласно изобретению пил равнна 50-53 единицы твердости по Роквеллу.The saw blades subjected to nitriding are first quenched in oil at 900-950 ° C and released at 540-570 ° C. After preferably polishing, liquid cyanidation is carried out for 10-25 minutes. In conclusion, the blades are spun and straightened. The hardness of the saw blades made according to the invention is equal to 50-53 Rockwell hardness units.

Как показали испытани , стойкость пил из сталей, полученных согласно изобретению , примерно на 75% выше, а именно повышаетс  от 3-3,5 до 5,5 ч.As tests have shown, the durability of saws from steels obtained according to the invention is about 75% higher, namely, it increases from 3-3.5 to 5.5 hours.

Пилы, обработанные согласно изобретению , благодар  образованию специальных нитридов в наружной зоне обладают в достаточной мере теми качествами, которые желательны дл  пил, предназначенных дл  древесины, а именно высокой износоустойчивостью , хорошей способностью скольжени , неспособностью к свариванию с инородными телами, хорошей сцепл емостью нитридного сло  и удовлетворительной способностью к деформации, этого сло  при разводке.Saws treated according to the invention, due to the formation of special nitrides in the outer zone, possess sufficiently those qualities that are desirable for saws designed for wood, namely high wear resistance, good sliding ability, inability to weld with foreign bodies, good adhesion of the nitride layer and satisfactory deformability of this layer during wiring.
