Abstract
Description
Изобретение относится к области черной металлургии и касается составов конструкционных сталей, которые могут быть использованы для изготовления различных деталей машин, в судостроении, тепловозостроении, автомобилестроении, тракторостроении и в других отраслях машиностроения.The invention relates to the field of ferrous metallurgy and relates to compositions of structural steels that can be used for the manufacture of various machine parts, in shipbuilding, diesel locomotive manufacturing, automotive, tractor manufacturing and other engineering industries.
Известна конструкционная сталь, содержащая, мас. %: углерод 0,13-0,18; кремний 0,17-0,37; марганец 0,8-2,0; хром 1,1-1,65; ванадий 0,2-0,4; никель 0,1-0,3; азот 0,025-0,05; алюминий 0,01-0,03; азот 0,04-0,12; барий 0,01-0,05; кальций 0,01-0,05; железо - остальное [1]. Предел прочности такой стали составляет 171-173,5 кгс/мм2.Known structural steel containing, by weight. %: carbon 0.13-0.18; silicon 0.17-0.37; manganese 0.8-2.0; chrome 1.1-1.65; vanadium 0.2-0.4; nickel 0.1-0.3; nitrogen 0.025-0.05; aluminum 0.01-0.03; nitrogen 0.04-0.12; barium 0.01-0.05; calcium 0.01-0.05; iron - the rest [1]. The tensile strength of such steel is 171-173.5 kgf / mm 2 .
Задачей изобретения является повышение прочности стали.The objective of the invention is to increase the strength of steel.
Технический результат достигается тем, что конструкционная сталь, содержащая углерод, кремний, марганец, хром, ванадий, никель, алюминий, кальций, железо, дополнительно включает молибден, медь и бор при следующем соотношении компонентов, мас. %: углерод 0,13-0,18; кремний 0,17-0,37; марганец 0,8-2,0; хром 1,1-1,65; ванадий 2,0-4,0; никель 1,0-3,0; алюминий 0,05-0,1; кальций 0,05-0,09; молибден 3,5-4,5; медь 1,6-2,0; бор 0,01-0,02; железо - остальное.The technical result is achieved by the fact that structural steel containing carbon, silicon, manganese, chromium, vanadium, nickel, aluminum, calcium, iron, additionally includes molybdenum, copper and boron in the following ratio of components, wt. %: carbon 0.13-0.18; silicon 0.17-0.37; manganese 0.8-2.0; chrome 1.1-1.65; vanadium 2.0-4.0; nickel 1.0-3.0; aluminum 0.05-0.1; calcium 0.05-0.09; molybdenum 3.5-4.5; copper 1.6-2.0; boron 0.01-0.02; iron is the rest.
В таблице приведены составы конструкционной стали.The table shows the composition of structural steel.
В составе стали компоненты проявляют себя следующим образом. Хром, ванадий, никель, молибден, медь обеспечивают коррозионную стойкость, прочность и твердость стали. Бор стабилизирует карбиды. Кальций и алюминий раскисляют сплав. Никель увеличивает прочность и пластичность стали, медь и ванадий препятствуют возникновению и развитию трещин.In the steel composition, the components manifest themselves as follows. Chrome, vanadium, nickel, molybdenum, copper provide corrosion resistance, strength and hardness of steel. Boron stabilizes carbides. Calcium and aluminum deoxidize the alloy. Nickel increases the strength and ductility of steel, copper and vanadium prevent the occurrence and development of cracks.
Сталь может быть выплавлена электродуговым способом. Основной исходный материал для выплавки стали - стальной лом.Steel can be smelted by electric arc. The main source material for steelmaking is steel scrap.
