Description
Изобретение относитс к области изыскани сталей, обладаюш,их высокими прочностными и пластическими свойствами, повышенной усталостной прочностью и релаксационной стойкостью . Стали предназначаютс дл поршневых колец быстроходных и мош.нЕ)Гх двигателей .The invention relates to the field of research of steels, possessing their high strength and plastic properties, increased fatigue strength and relaxation resistance. The steels are intended for high-speed piston rings and mosh.nE) Gkh engines.
Известна сгаль, содержаща углерод, кремний , марганец, хром, вольфрам, железо.Calcium containing carbon, silicon, manganese, chromium, tungsten, and iron are known.
Предложенна сталь отличаетс от известной повышенным содержанием хрома. Это обеспечивает повышение теп.пог,тойкости и предела упругости.The proposed steel differs from the known high chromium content. This provides an increase in heat stress, hardness and elastic limit.
Сталь имеет следующий состав (в %):Steel has the following composition (%):
0,61-0,69 1,5-2,00.61-0.69 1.5-2.0
0,85-1,1 1,6-1,8 0,7-0,95 Остальное0.85-1.1 1.6-1.8 0.7-0.95 Else
После закалки от 950°С и отпуска при 650°С сталь обладает высокими механическими свойствами , сохран ющимис до температуры 450°С.After quenching from 950 ° C and tempering at 650 ° C, the steel has high mechanical properties that are maintained at a temperature of 450 ° C.
Предел прочности стали 134 кг/мм ; предел текучести 110 кг/мм-; относите.1ьное удлинение 16,4%; относительное сужение 34,4%; ударна в зкость 3,5 кгм/см.The tensile strength of steel is 134 kg / mm; yield strength of 110 kg / mm; The relative elongation is 16.4%; relative narrowing of 34.4%; impact viscosity 3.5 kgm / cm.
