Abstract
Description
Изобретение относится к области черной металлургии и касается составов сталей, которые могут быть использованы для изготовления инструмента холодного деформирования.The invention relates to the field of ferrous metallurgy and relates to compositions of steels that can be used for the manufacture of cold forming tools.
Известна штамповая сталь, содержащая, мас.%: углерод 0,45-0,55; кремний 1,05-1,25; марганец 14,5-15,5; хром 7,5-8,5; ванадий 1,8-2,0; цирконий 0,2-0,4; азот 0,15-0,45; бор 0,004-0,008; кальций 0,01-0,02; тантал 0,015-0,03; железо - остальное [1].Known die steel, containing, wt.%: Carbon 0.45-0.55; silicon 1.05-1.25; manganese 14.5-15.5; chrome 7.5-8.5; vanadium 1.8-2.0; zirconium 0.2-0.4; nitrogen 0.15-0.45; boron 0.004-0.008; calcium 0.01-0.02; tantalum 0.015-0.03; iron - the rest [1].
Задачей изобретения является повышение твердости стали.The objective of the invention is to increase the hardness of steel.
Технический результат достигается тем, что штамповая сталь, содержащая углерод, кремний, марганец, хром, ванадий, цирконий, азот, бор, кальций, тантал, железо, дополнительно содержит никель, гафний и цинк, при следующем соотношении компонентов, мас.%: углерод 0,4-0,6; кремний 0,8-1,2; марганец 14,5-15,5; хром 7,5-8,5; ванадий 1,8-2,2; цирконий 0,08-0,12; азот 0,02-0,03; бор 0,1-0,13; кальций 0,007-0,009; тантал 1,5-2,0; никель 3,0-3,4; гафний 0,4-0,6; цинк 0,001-0,002; железо - остальное.The technical result is achieved by the fact that stamp steel containing carbon, silicon, manganese, chromium, vanadium, zirconium, nitrogen, boron, calcium, tantalum, iron, additionally contains nickel, hafnium and zinc, in the following ratio, wt.%: Carbon 0.4-0.6; silicon 0.8-1.2; manganese 14.5-15.5; chrome 7.5-8.5; vanadium 1.8-2.2; zirconium 0.08-0.12; nitrogen 0.02-0.03; boron 0.1-0.13; calcium 0.007-0.009; tantalum 1.5-2.0; nickel 3.0-3.4; hafnium 0.4-0.6; zinc 0.001-0.002; 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 и марганец обеспечивают коррозионную стойкость, прочность и твердость стали. Никель увеличивает прочность и пластичность сплава, тантал - коррозионную стойкость сплава В химически связанном состояний с ванадием азот, образуя нитриды, становится легирующим элементом, улучшающим структуру и механические свойства стали. Бор стабилизирует карбиды. Кальций раскисляет сталь. Цинк способствуют измельчению зернаIn the steel composition, the components manifest themselves as follows. Chromium, hafnium and manganese provide corrosion resistance, strength and hardness of steel. Nickel increases the strength and ductility of the alloy, tantalum - the corrosion resistance of the alloy. In chemically bonded states with vanadium, nitrogen, forming nitrides, becomes an alloying element that improves the structure and mechanical properties of steel. Boron stabilizes carbides. Calcium deoxidizes steel. Zinc contributes to grain refinement
Сталь может быть выплавлена электродуговым способом. Основной исходный материал для выплавки стали - стальной лом. Термическая обработка стали включает нагрев до температуры 1000°С и отпуск при температуре 200°С.Steel can be smelted by electric arc. The main source material for steelmaking is steel scrap. Heat treatment of steel includes heating to a temperature of 1000 ° C and tempering at a temperature of 200 ° C.
