Abstract
Description
Изобретение относится к металлургии, в частности к сталям, применяемым в машиностроении, станкостроении и других отраслях. The invention relates to metallurgy, in particular to steels used in mechanical engineering, machine tool industry and other industries.
Известна сталь, включающая углерод, кремний, марганец и другие ингредиенты. Steel is known, including carbon, silicon, manganese and other ingredients.
Известна сталь, включающая следующие ингредиенты, мас. % : углерод 0,07-0,2; хром 12,8-14,9; бор 0,001-0,004; кальций 0,001-0,02; медь 0,3-1,1; железо - остальное. Такая сталь имеет повышенную коррозионно-усталостную стойкость при кавитации, но низкие механические свойства, что ограничивает область ее применения. Known steel, including the following ingredients, wt. %: carbon 0.07-0.2; chrome 12.8-14.9; boron 0.001-0.004; calcium 0.001-0.02; copper 0.3-1.1; iron is the rest. Such steel has increased corrosion and fatigue resistance during cavitation, but low mechanical properties, which limits its scope.
Цель изобретения - повышение механических свойств стали. The purpose of the invention is to increase the mechanical properties of steel.
Для достижения цели в состав стали дополнительно вводят нитрид кремния, при следующем соотношении ингредиентов, мас. %: углерод 0,25-0,35; хром 13,0-15,0; бор 0,01-0,02; кальций 0,001-0,02; медь 0,5-0,8; нитрид кремния 1,5-2,1; железо - остальное. To achieve the goal, silicon nitride is additionally introduced into the steel composition, in the following ratio of ingredients, wt. %: carbon 0.25-0.35; chrome 13.0-15.0; boron 0.01-0.02; calcium 0.001-0.02; copper 0.5-0.8; silicon nitride 1.5-2.1; iron is the rest.
В таблице приведены примерные составы стали. The table shows approximate compositions of steel.
Ожидается, что предел прочности предложенной стали составит, кг/мм2: для 1-го состава - 85, для 2-3-го составов -93. Предел прочности стали-прототипа - 65-71 кг/мм2. Предел текучести предложенной стали, кг/мм2: для 1-го состава - 70; для 2-го состава - 72; для 3-го состава - 75; известной стали-прототипа - 31-35. Ожидается незначительное (на 2-3%) снижение коррозионно-усталостной стойкости стали.It is expected that the tensile strength of the proposed steel will be, kg / mm 2 : for the 1st composition - 85, for the 2nd-3rd composition -93. The tensile strength of the steel of the prototype is 65-71 kg / mm 2 . The yield strength of the proposed steel, kg / mm 2 : for the 1st composition - 70; for the 2nd composition - 72; for the 3rd composition - 75; famous prototype steel - 31-35. A slight (2-3%) decrease in the corrosion and fatigue resistance of steel is expected.
