Abstract
Description
Изобретение относится к области черной металлургии, а именно к составам сталей, которые могут быть использованы для изготовления деталей машин и оборудования для штамповки и литья пластмасс.The invention relates to the field of ferrous metallurgy, and in particular to compositions of steels that can be used for the manufacture of machine parts and equipment for stamping and molding of plastics.
Известна инструментальная сталь, содержащая, мас.%: углерод ≤ 2,0; кремний ≤ 5,0; марганец 10,0-40,0; хром ≤ 5,0; титан ≤ 1,0; бор ≤ 0,1; алюминий ≤ 5,0; медь ≤ 5,0; железо и неизбежные примеси - остальное [1].Known tool steel, containing, wt.%: Carbon ≤ 2.0; silicon ≤ 5.0; manganese 10.0-40.0; chrome ≤ 5.0; titanium ≤ 1.0; boron ≤ 0.1; aluminum ≤ 5.0; copper ≤ 5.0; iron and inevitable impurities - the rest [1].
Задачей изобретения является повышение ударной вязкости стали.The objective of the invention is to increase the toughness of steel.
Технический результат достигается тем, что в инструментальной стали, содержащей углерод, кремний, марганец, хром, титан, бор, алюминий, медь, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,04-0,06; кремний 0,04-0,06; марганец 8,0-12,0; хром 8,0-12,0; титан 2,0-3,0; бор 0,04-0,06; алюминий 0,4-0,6; медь 0,5-1,0; железо - остальное.The technical result is achieved in that in tool steel containing carbon, silicon, manganese, chromium, titanium, boron, aluminum, copper, iron, the components are in the following ratio, wt.%: Carbon 0.04-0.06; silicon 0.04-0.06; manganese 8.0-12.0; chrome 8.0-12.0; titanium 2.0-3.0; boron 0.04-0.06; aluminum 0.4-0.6; copper 0.5-1.0; iron is the rest.
В таблице приведены составы инструментальной стали.The table shows the composition of tool steel.
Повышение ударной вязкости стали достигается за счет комплексного влияния компонентов, входящих в ее состав. Хром обеспечивает твердость, теплостойкость и коррозионную стойкость стали. Бор стабилизирует карбиды. Титан упрочняет твердый раствор. Медь увеличивает прочность и пластичность сплава. Алюминий выполняет функцию раскислителя, способствует образованию мелкозернистой структуры стали.An increase in the toughness of steel is achieved due to the complex effect of the components included in its composition. Chromium provides hardness, heat resistance and corrosion resistance of steel. Boron stabilizes carbides. Titanium strengthens the solid solution. Copper increases the strength and ductility of the alloy. Aluminum acts as a deoxidizing agent, contributes to the formation of a fine-grained steel structure.
Сталь может быть выплавлена в индукционных вакуумных печах. Основной исходный материал для выплавки стали - стальной лом, специально приготовленная шихта.Steel can be smelted in induction vacuum furnaces. The main source material for steelmaking is steel scrap, a specially prepared charge.
Термообработка стали проводится по режиму: отпуск при 750-900°С в течение 2 ч, закалка в масле при 1200°С.Heat treatment of steel is carried out according to the regime: tempering at 750-900 ° C for 2 hours, quenching in oil at 1200 ° C.
