Abstract
Description
Изобретение относится к области черной металлургии и касается составов сталей, которые могут быть использованы для изготовления инструмента горячего деформирования.The invention relates to the field of ferrous metallurgy and relates to compositions of steels that can be used for the manufacture of hot deformation tools.
Известна штамповая сталь, содержащая, мас. %: углерод 0,2-0,3; кремний 0,8-1,2; марганец 0,8-1,2; хром 4,5-5,5; никель 0,8-1,2; молибден 1,2-1,5; ванадий 0,3-0,6; барий 0,001-0,006; азот 0,012-0,06; железо - остальное [1].Known die steel containing, by weight. %: carbon 0.2-0.3; silicon 0.8-1.2; manganese 0.8-1.2; chrome 4.5-5.5; nickel 0.8-1.2; molybdenum 1.2-1.5; vanadium 0.3-0.6; barium 0.001-0.006; nitrogen 0.012-0.06; iron - the rest [1].
Задачей изобретения является повышение теплостойкости стали.The objective of the invention is to increase the heat resistance of steel.
Технический результат достигается тем, что литая штамповая сталь, содержащая углерод, кремний, марганец, хром, никель, молибден, ванадий, барий, железо, дополнительно содержит сурьму, серебро, медь, алюминий, причем компоненты находятся при следующем соотношении, мас. %: углерод 0,2-0,3; кремний 0,5-1,0; марганец 0,8-1,2; хром 6,5-7,0; никель 2,0-2,5; молибден 0,35-0,45; ванадий 0,8-1,2; барий 0,002-0,004; сурьма 0,002-0,004; серебро 0,02-0,04; медь 1,0-1,6; алюминий 0,2-0,25; железо - остальное.The technical result is achieved by the fact that cast die steel containing carbon, silicon, manganese, chromium, nickel, molybdenum, vanadium, barium, iron, additionally contains antimony, silver, copper, aluminum, and the components are in the following ratio, wt. %: carbon 0.2-0.3; silicon 0.5-1.0; manganese 0.8-1.2; chrome 6.5-7.0; nickel 2.0-2.5; molybdenum 0.35-0.45; vanadium 0.8-1.2; barium 0.002-0.004; antimony 0.002-0.004; silver 0.02-0.04; copper 1.0-1.6; aluminum 0.2-0.25; iron is the rest.
В таблице приведены составы литой штамповой стали.The table shows the composition of die cast steel.
Теплостойкость стали (сохранение твердости не менее 40 HRC в течение 4 ч) составит ~850°C для всех приведенных в таблице составов.The heat resistance of steel (maintaining a hardness of at least 40 HRC for 4 hours) will be ~ 850 ° C for all the compositions listed in the table.
В составе стали компоненты проявляют себя следующим образом. Хром, ванадий, никель, молибден, медь, ниобий, фосфор и марганец обеспечивают теплостойкость стали. Никель улучшает металлическую основу стали. Медь, сурьма, серебро, алюминий способствует равномерному нагреву и охлаждению сплава. Барий раскисляет сталь. Алюминий препятствует росту окалины, тормозит развитие трещин при перепадах температур.In the steel composition, the components manifest themselves as follows. Chrome, vanadium, nickel, molybdenum, copper, niobium, phosphorus and manganese provide heat resistance of steel. Nickel improves the metal base of steel. Copper, antimony, silver, aluminum promotes uniform heating and cooling of the alloy. Barium deoxidizes steel. Aluminum inhibits the growth of scale, inhibits the development of cracks at temperature extremes.
Сталь может быть выплавлена электродуговым способом. Основной исходный материал для выплавки стали - стальной лом. Термическая обработка стали включает закалку от 1050°C в масле и отпуск при 570°C.Steel can be smelted by electric arc. The main source material for steelmaking is steel scrap. Heat treatment of steel includes quenching from 1050 ° C in oil and tempering at 570 ° C.
