Description
Изобретение относится к области черной металлургии, в частности к составам сталей, используемых для изготовления режущего инструмента, работающего при высоких скоростях резания.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels used for the manufacture of a cutting tool operating at high cutting speeds.
Известна быстрорежущая сталь, содержащая, мас.%: углерод 0,4-0,8; кремний ≤2,0; марганец ≤2,0; хром 2,0-5,0; вольфрам 2,0-15,0; молибден ≤7,5; ванадий 0,1-2,0; никель ≤2,0; кобальт ≤10,0; алюминий ≤1,5; железо - остальное [1].Known high-speed steel, containing, wt.%: Carbon 0.4-0.8; silicon ≤2.0; Manganese ≤2.0; chrome 2.0-5.0; tungsten 2.0-15.0; molybdenum ≤7.5; vanadium 0.1-2.0; nickel ≤2.0; cobalt ≤10.0; aluminum ≤1.5; iron - the rest [1].
Задачей изобретения является повышение ударной вязкости стали.The objective of the invention is to increase the toughness of steel.
Технический результат достигается тем, что быстрорежущая сталь, содержащая углерод, кремний, марганец, хром, вольфрам, молибден, ванадий, никель, кобальт, алюминий, железо, дополнительно содержит рений при следующем соотношении компонентов, мас.%: углерод 0,3-0,6; кремний 0,03-0,08; марганец 0,1-0,2; хром 5,5-6,5; вольфрам 5,5-6,5; молибден 5,5-6,5; ванадий 5,5-6,5; никель 5,5-6,5; кобальт 5,5-6,5; алюминий 0,05-0,1; рений 5,5-6,5; железо - остальное.The technical result is achieved by the fact that high-speed steel containing carbon, silicon, manganese, chromium, tungsten, molybdenum, vanadium, nickel, cobalt, aluminum, iron, additionally contains rhenium in the following ratio of components, wt.%: Carbon 0.3-0 , 6; silicon 0.03-0.08; manganese 0.1-0.2; chrome 5.5-6.5; tungsten 5.5-6.5; molybdenum 5.5-6.5; vanadium 5.5-6.5; nickel 5.5-6.5; cobalt 5.5-6.5; aluminum 0.05-0.1; rhenium 5.5-6.5; iron is the rest.
В таблице приведены составы быстрорежущей стали.The table shows the compositions of high speed steel.
Повышение ударной вязкости быстрорежущей стали обусловлено комплексным влиянием компонентов, входящих в ее состав. Вольфрам и рений увеличивают твердость и работоспособность стали при высоких скоростях резания. Молибден повышает прочностные характеристики стали, увеличивает твердость, делает ее теплоустойчивой. Ванадий увеличивает прочность и вязкость стали. Хром и марганец повышают твердость стали, но марганец придает стали тепловую хрупкость, которая устраняется введением никеля. Никель в сочетании с кобальтом снижает склонность стали к образованию трещин. Алюминий способствует получению мелкозернистой структуры.The increase in impact strength of high speed steel is due to the complex effect of the components that make up its composition. Tungsten and rhenium increase the hardness and performance of steel at high cutting speeds. Molybdenum increases the strength characteristics of steel, increases hardness, makes it heat-resistant. Vanadium increases the strength and toughness of steel. Chrome and manganese increase the hardness of steel, but manganese gives the steel thermal brittleness, which is eliminated by the introduction of nickel. Nickel combined with cobalt reduces the tendency of steel to crack. Aluminum contributes to obtaining a fine-grained structure.
Сталь может быть выплавлена в электропечах. Нагрев быстрорежущей стали под закалку производят до температур 1280-1300°С для наиболее полного растворения карбидов. После закалки сталь подвергают отпуску при температуре 560-580°С. Сталь после закалки и отпуска может быть подвержена обработке холодом.Steel can be smelted in electric furnaces. Heating of high-speed steel for hardening is carried out to temperatures of 1280–1300 ° C for the most complete dissolution of carbides. After hardening, the steel is subjected to tempering at a temperature of 560-580 ° C. Steel after hardening and tempering may be subject to cold working.
