Description

снижение прочностных свойств стали, что обеспечивает минимальные ус или  при холодной навивке и как следствие качественную навивку;a decrease in the strength properties of steel, which ensures minimal whiskers or during cold winding and, as a result, high-quality winding;

снижение прочностных свойств приводит к увеличению срока службы оснастки, уменьшает ее износ;the decrease in strength properties leads to an increase in the service life of the equipment, reduces its wear;

меньша  по сравнению с известными способами продолжительность процессаshorter process time compared to known methods

обеспечивает повышение производительности процесса и отсутствие обезуглеро- женного сло .provides an increase in process productivity and the absence of a decarburized layer.
