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 0,6-1,2; марганец 0,25-0,6; хром 4,5-5,5; кальций 0,001-0,01; титан 0,01-0,1; иттрий 0,001-0,01; железо - остальное [1].Known die steel containing, by weight. %: carbon 0.2-0.3; silicon 0.6-1.2; manganese 0.25-0.6; chrome 4.5-5.5; calcium 0.001-0.01; titanium 0.01-0.1; yttrium 0.001-0.01; iron - the rest [1].
Задачей изобретения является повышение термостойкости стали.The objective of the invention is to increase the heat resistance of steel.
Технический результат достигается тем, что штамповая сталь, содержащая углерод, кремний, марганец, хром, кальций, титан, иттрий, железо, дополнительно включает гафний, алюминий и ниобий, причем компоненты находятся при следующем соотношении, мас. %: углерод 0,15-0,25; кремний 0,15-0,25; марганец 0,5-1,0; хром 4,5-5,5; кальций 0,003-0,008; титан 0,1-0,15; иттрий 0,01-0,03; гафний 4,3-4,8; алюминий 0,15-0,25; ниобий 0,1-0,15; железо - остальное.The technical result is achieved in that the stamped steel containing carbon, silicon, manganese, chromium, calcium, titanium, yttrium, iron, further includes hafnium, aluminum and niobium, and the components are in the following ratio, wt. %: carbon 0.15-0.25; silicon 0.15-0.25; manganese 0.5-1.0; chrome 4.5-5.5; calcium 0.003-0.008; titanium 0.1-0.15; yttrium 0.01-0.03; hafnium 4.3-4.8; aluminum 0.15-0.25; niobium 0.1-0.15; iron is the rest.
В таблице приведены составы штамповой стали.The table shows the composition of die steel.
В составе стали компоненты проявляют себя следующим образом. Хром, гафний, ниобий обеспечивают термостойкость и твердость стали. Гафний и алюминий препятствуют возникновению трещин при перепадах температур. Титан способствует измельчению зерна. Кальций и иттрий раскисляют сталь.In the steel composition, the components manifest themselves as follows. Chromium, hafnium, niobium provide heat resistance and hardness of steel. Hafnium and aluminum prevent cracking during temperature changes. Titanium helps to chop grain. Calcium and yttrium deoxidize steel.
Термическая обработка стали включает закалку от 1050°C в масле и отпуск при 570°C.Heat treatment of steel includes quenching from 1050 ° C in oil and tempering at 570 ° C.
