Description

Изобретение относитс к области металлургии , в частности к .изысканию конструкционных сталей, обладающих повышенными механическими свойствами. Известна сталь, содержаща углерод, кремний , марганец, хром, никель и молибден, после закалки и отпуска имеет следующие свойства: Предел прочности, кг/мм Предел текучести, кг/мм Относительное удлинение, % Относительное сужение, % Ударна в зкость, кгм/см При термообработке сталь имеет значительные короблени . С целью повышени механических свойств, а также уменьшени короблени и повыщени прокаливаемости в состав предложенной стали введены алюминий, медь и ниобий при следующем соотношении ко.мпонентов, %: не более 0,06 Углерод Кремний 0,15-0,4 Марганец 0,15-0,60 3,5-9,0 Никель 1,5-3,2 1,0-3,0 0,1-2,5 0,05-1,1 0,001-0,05 Ниобий не более 0,015 Сера не более 0,015 Фосфор Железо остальное. Предложенна сталь имеет высокие прочностные свойства: Предел прочности, кг/мм 107-139 Предел текучести, кг/мм 93-131 Относительное удлинение, % 13-17 Относительное сужение, % 54-65 Ударна в зкость, кгм/см 8-10 Прокаливаемость стали более 100 мм. Предложенна сталь вл етс дисперсионно твердеющей, поэтому окончательную механическую ее обработку можно производить после закалки, а затем изделие подвергают только старению при 475-550°С, что значительно уменьшает коробление стали в процессе термической обработки. Предмет изобретени Конструкционна сталь, содержаща углерод , кремний, марганец, хром, никель, молибден и железо, отличающа с тем, что, с целью повышени механических характеристик, прокаливаемости , а также уменьшени короблени издели при термической обработке, в нее введены алюминий, медь и ниобий при следующем соотношении компонентов, %: 3 Углеродне более 0,06 Кремний0,15-0,4 Марганец0,15-0,60 Хром3.5-9,0 Никель1,5-3,25 Молибден1,0-3,0 299561 4 Медь 0,1-2,5 Алюминий 0,05-1,1 Ниобий 0,001-0,05 Серане более 0,015 Фосфорне более 0,015 Железо остальное.The invention relates to the field of metallurgy, in particular to the search for structural steels with enhanced mechanical properties. Known steel containing carbon, silicon, manganese, chromium, nickel and molybdenum, after quenching and tempering has the following properties: Strength, kg / mm Yield strength, kg / mm Elongation,% Relative narrowing,% Impact strength, kgm / cm. During heat treatment, steel has considerable warping. In order to improve the mechanical properties, as well as reduce the warping and hardenability, aluminum, copper and niobium are introduced into the composition of the proposed steel in the following ratio of co-components,%: not more than 0.06 Silicon carbon 0.15-0.4 Manganese 0.15 -0.60 3.5-9.0 Nickel 1.5-3.2 1.0-3.0 0.1-2.5 0.05-1.1 0.001-0.05 Niobium not more than 0.015 Sulfur no more than 0.015 Phosphorus Iron the rest. The proposed steel has high strength properties: Strength, kg / mm 107-139 Yield strength, kg / mm 93-131 Relative elongation,% 13-17 Relative narrowing,% 54-65 Shock viscosity, kgm / cm 8-10 Hardenability steel more than 100 mm. The proposed steel is dispersively hardening, therefore, its final mechanical processing can be performed after quenching, and then the product is subjected only to aging at 475-550 ° C, which significantly reduces the distortion of the steel during the heat treatment process. Object of the invention Structural steel containing carbon, silicon, manganese, chromium, nickel, molybdenum and iron, characterized in that, in order to increase the mechanical characteristics, hardenability, as well as reduce the distortion of the product during heat treatment, aluminum, copper and niobium in the following ratio of components,%: 3 Carbon over 0.06 Silicon0.15-0.4 Manganese0.15-0.60 Chromium3.5-9.0 Nickel1.5-3.25 Molybdenum1.0-3.0 299561 4 Copper 0.1-2.5 Aluminum 0.05-1.1 Niobium 0.001-0.05 Serane more than 0.015 Phosphorous more than 0.015 Iron the rest.
