Description

Изобретение относитс  к области изыска низколегированных сталей, предназначенн дл  изготовлени  деталей несущей систе тракторов и сельхозмашин. Известна сталь, содержаща  углерод, м ганец, кремний, хром, ванадий, титан, а миний, бор и железо. Предложенна  сталь отличаетс  от изв ной тем, что, с целью повышени  механи ских свойств, в нее введены никель и азот соотношении компонентов следующем вес. %): 0,16-0,27 Углерод 0,3-1,2 Марганец 0,2-0,8 Кремний 0,15-0,35 Хром Никель 0,03-0,5 Ванадий 0,03-0,2 Титан 0,04-0,15 Алюминий 0,02-0,3 Азот 0,0015-0,06 Бор Остальное Железо Механические свойства описываемой ст следующие: Предел прочности, кгс/мм 60,5-66 Предел текучести, кгс/мм 44-53 Относительное удлинение, % 25-26 Относительное сужение, % 44-46 Ударна  в зкость, кгм/см 5-6 Твердость, HRC43-44 Предмет изобретени  аль, содержаи1,а  углерод, марганец, ний, хром, ванадий, титан, алюминий, бор елезо, отличающа с  тем, что, с цеповышени  механических свойств, в нее следующем соотноены никель и азот при ии компонентов (в вес. Углерод 0,16-0,27 Марганец 0,3-1,2 0,2-0,8 Кремний 0,15-0,35 Хром Никель 0,3-1 0,03-0,5 Ванадий 0,03-0,2 0,04-0,15 Алюминий 0,02-0,3 0,0015-0,06 Бор Остальное ЖелезоThe invention relates to the field of searching for low alloy steels, intended for the manufacture of parts of a carrier system of tractors and agricultural machinery. Famous steel containing carbon, manganese, silicon, chromium, vanadium, titanium, and minium, boron, and iron. The proposed steel differs from the fact that, in order to improve the mechanical properties, nickel and nitrogen are introduced into it. The ratio of the components is as follows. %): 0.16-0.27 Carbon 0.3-1.2 Manganese 0.2-0.8 Silicon 0.15-0.35 Chromium Nickel 0.03-0.5 Vanadium 0.03-0, 2 Titanium 0.04-0.15 Aluminum 0.02-0.3 Nitrogen 0.0015-0.06 Bor Additional Iron The mechanical properties of the described article are as follows: Strength, kgf / mm 60.5-66 Yield strength, kgf / mm 44-53 Relative elongation,% 25-26 Relative constriction,% 44-46 Shock viscosity, kgm / cm 5-6 Hardness, HRC43-44 The subject matter of the invention is al Titanium, aluminum, boron, characterized in that, from the chain of mechanical properties, in it the following ratio of nickel and nitrogen is of these components (in weight.
