Изобретение относитс к области черной металлургии, в частности к литейным стал м. Наиболее близкой к предлагаемой по технической сущности и достигав- 5 мому эффекту вл етс сталь, содержаща , вес,%: Углерод 0,28-0,40 Марганец0,6-1,5 Кремний0,17-0,60 Алюминий0,005-0,1 Титан0,005-0,8 Бор0,0005-0,006 Кальций0,0001-0,004 Магний0,0001-0,009 15 Хром0,1-1,0 ЖелезоОстальное 1. целью изобретени вл етс повышейие пластических свойств и ударной в зкости стали.20 Поставленна цель достигаетс тем что предлагаема сталь дополнительно содержит ванадий и барий при следующем соотношении компонентов, вес.%: УглеродО,15-0,50 25 Кремний0,2-0,5 Марганец0,9-1,5 Алюминий0,01-0,08 Хром0,05-0,45 Титан0,005-0,04 30 10 0,0001-0,0009 Кальций 0,0005-0,05 Магний 0,02-0,2 Ванадий , 0,0001-0,0009 Барий Железо -Остальное Дл определени механических свойств были отлиты стандартные трефообразные пробы. Образцы были подвергнуты термической обработке: закалка при с последующим отпуском при . Составы исследуемых сталей (предлагаемой и известной) приведены в табл.1. Результаты по механическим испытани м исследуемых сталей приведены в табл,2, Механические испытани образцов из исследуемых сталей показали, что по прочностным свойствам разницы между результатами нет. По пластическим характеристикам (o,4i) отмечаютс более высокие показатели у предлагаемой стали: в среднем о - на 19% (OTR) и Ф - на 19% (отн.) , Значени ударной в зкости предлагаемой стали повышаютс в среднем на 31,1% (отн.) при +20 Си на 34% (отн.) при -60°С.The invention relates to the field of ferrous metallurgy, in particular, to casting steels, m. The closest to the proposed technical essence and the achieved effect is steel containing, in weight,%: Carbon 0.28-0.40 Manganese 0.6-1 , 5 Silicon0.17-0.60 Aluminum0.005-0.1 Titanium0.005-0.8 Bor0,0005-0.006 Calcium0,0001-0.004 Magnesium0,0001-0.009 15 Chrome0.1-1.0 IronEstal 1 the invention is to improve the plastic properties and toughness of steel. 20 The goal is achieved by the fact that the proposed steel additionally contains vanadium and barium in the following ratio components, wt.%: Carbon, 15-0.50 25 Silicon0.2-0.5 Manganese0.9-1.5 Aluminum0.01-0.08 Chromium0.05-0.45 Titanium0.005-0.04 30 10 0.0001-0.0009 Calcium 0.0005-0.05 Magnesium 0.02-0.2 Vanadium, 0.0001-0,0009 Barium Iron-Others Standard trefe-shaped samples were cast to determine the mechanical properties. The samples were subjected to heat treatment: quenching with subsequent release at. The compositions of the investigated steels (proposed and known) are given in table 1. The results of the mechanical tests of the studied steels are given in Table 2, The mechanical tests of samples of the studied steels showed that, according to the strength properties, there is no difference between the results. According to the plastic characteristics (o, 4i), there are higher rates for the proposed steel: on average o - by 19% (OTR) and F - by 19% (rel.), The toughness values of the proposed steel increase by an average of 31.1 % (rel.) at +20 Cu at 34% (rel.) at -60 ° C.
