Одним применением этой стали согласно изобретению является получение деталей машин, в частности для автомобилестроения, причем такие детали после ковки в штампе и ускоренного контролируемого охлаждения имеют преимущественно бейнитную структуру с выделениями специальных карбидов и/или нитридов.One application of this steel according to the invention is the production of machine parts, in particular for the automotive industry, and such parts after forging in a die and accelerated controlled cooling have a predominantly bainitic structure with precipitates of special carbides and / or nitrides.
Для полученных таким образом деталей согласно п.4 предусматривается, что предел текучести после ускоренного контролируемого охлаждения от деформационного нагрева составляет более 620 Н/мм2.For the parts thus obtained, according to claim 4, it is provided that the yield strength after accelerated controlled cooling from deformation heating is more than 620 N / mm 2 .
При этом предел прочности при растяжении согласно п.5 после ускоренного контролируемого охлаждения от деформационного нагрева должен составлять от 800 до 1100 Н/мм2.Moreover, the tensile strength according to claim 5 after accelerated controlled cooling from deformation heating should be from 800 to 1100 N / mm 2 .
Предпочтительно отношение предела текучести к пределу прочности после ускоренного контролируемого охлаждения от деформационного нагрева составляет более 70%.Preferably, the ratio of yield strength to tensile strength after accelerated controlled cooling from deformation heating is more than 70%.
Согласно п.7 предусматривается, что предельное удлинение после ускоренного контролируемого охлаждения от деформационного нагрева составляет более 10%.According to paragraph 7, it is provided that the ultimate elongation after accelerated controlled cooling from deformation heating is more than 10%.
Согласно п.8 предусмотрено, что относительное сужение при разрыве после ускоренного контролируемого охлаждения от деформационного нагрева составляет более 40%.According to paragraph 8, it is provided that the relative narrowing at break after accelerated controlled cooling from deformation heating is more than 40%.
Согласно п.9 работа на ударный изгиб с надрезом (надрез согласно ΌνΜ, комнатная температура) после ускоренного контролируемого охлаждения от деформационного нагрева составляет более 25 Дж.According to paragraph 9, the work on impact bending with a notch (notch according to ΌνΌ, room temperature) after accelerated controlled cooling from deformation heating is more than 25 J.
Согласно п.10 предлагается, что коэффициенты вязкости можно регулировать ступенчатым охлаждением, сначала с высокой скоростью охлаждения и стадией выдерживания в области бейнита или последующей обработкой старением.According to claim 10, it is proposed that the viscosity coefficients can be controlled by stepwise cooling, first with a high cooling rate and a holding step in the bainite region or subsequent aging treatment.
Деталь согласно п.11 должна быть пригодной для цементации с последующей закалкой и отпуском и для нитроцементации.The item according to claim 11 should be suitable for cementation with subsequent hardening and tempering and for nitrocarburizing.
Наконец, механические свойства как катанной заготовки для ковки, так и кованой детали можно устанавливать путем термообработки.Finally, the mechanical properties of both the rolled blank for forging and the forged part can be set by heat treatment.
