Abstract
Description
Изобретение относится к области металлургии, в частности к составам стали, которая может быть использована в машиностроении.The invention relates to the field of metallurgy, in particular to compositions of steel, which can be used in mechanical engineering.
Известна сталь, содержащая, мас.%: углерод 0,11-0,2; кремний <3,0; марганец 0,6-2,0; хром <0,5; никель <2,0; ванадий <0,12; молибден <0,5; кальций <0,001; барий <0,001; медь <2,0; железо - остальное [1].Known steel containing, wt.%: Carbon 0.11-0.2; silicon <3.0; manganese 0.6-2.0; chrome <0.5; nickel <2.0; vanadium <0.12; molybdenum <0.5; calcium <0.001; barium <0.001; copper <2.0; iron - the rest [1].
Задача изобретения состоит в улучшении обрабатываемости стали резанием.The objective of the invention is to improve the machinability of steel by cutting.
Технический результат достигается тем, что в стали, содержащей углерод, кремний, марганец, хром, никель, ванадий, молибден, кальций, барий, медь, железо, компоненты находятся при следующем соотношении, мас.%: углерод 0,17-0,23; кремний 0,1-0,17; марганец 0,1-0,2; хром 0,1-0,2; никель 0,4-0,8; ванадий 0,05-0,15; молибден 1,0-1,5; кальций 0,005-0,007; барий 0,005-0,007; медь 2,5-3,5; железо - остальное.The technical result is achieved in that in steel containing carbon, silicon, manganese, chromium, nickel, vanadium, molybdenum, calcium, barium, copper, iron, the components are in the following ratio, wt.%: Carbon 0.17-0.23 ; silicon 0.1-0.17; manganese 0.1-0.2; chrome 0.1-0.2; nickel 0.4-0.8; vanadium 0.05-0.15; molybdenum 1.0-1.5; calcium 0.005-0.007; barium 0.005-0.007; copper 2.5-3.5; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В составе стали компоненты проявляют себя следующим образом. Хром стабилизирует карбиды, уменьшает транскристаллизацию. Молибден, никель и медь упрочняют твердый раствор. Кальций, барий и ванадий раскисляют сталь, придают ее структуре мелкозернистость.In the steel composition, the components manifest themselves as follows. Chromium stabilizes carbides, reduces transcrystallization. Molybdenum, nickel and copper harden the solid solution. Calcium, barium and vanadium deoxidize the steel, give its structure a fine grain.
Сталь может быть выплавлена кислым конвертерным способом на воздушном или кислородном дутье. Основной исходный материал для выплавки стали - бессемеровский чугун и стальной лом.Steel can be melted using an acidic converter method using air or oxygen blasting. The main source material for steelmaking is Bessemer cast iron and steel scrap.
Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
