Description

Изобретение относится к области черной металлургии, в частности к составам сталей, используемых для изготовления деталей, работающих в условиях трения и интенсивного износа.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels used for the manufacture of parts operating in conditions of friction and intense wear.

Известна сталь, содержащая, мас.%: углерод 0,5-0,65; кремний 0,2-0,4; марганец 0,6-0,8; ванадий 0,05-0,1; медь 0,05-0,6; никель 0,015-0,25; хром 0,01-0,2; фосфор 0,01-0,035; сера 0,02-0,04; бор 0,0008-0,003; алюминий 0,005-0,1; железо - остальное [1].Known steel containing, wt.%: Carbon 0.5-0.65; silicon 0.2-0.4; manganese 0.6-0.8; vanadium 0.05-0.1; copper 0.05-0.6; nickel 0.015-0.25; chromium 0.01-0.2; phosphorus 0.01-0.035; sulfur 0.02-0.04; boron 0.0008-0.003; aluminum 0.005-0.1; iron - the rest [1].

Задачей изобретения является повышение износостойкости стали.The objective of the invention is to increase the wear resistance of steel.

Технический результат достигается тем, что сталь, содержащая углерод, кремний, марганец, медь, никель, хром, бор, железо, дополнительно содержит кобальт и самарий при следующем соотношении компонентов, мас.%: углерод 2,0-2,05; кремний 2,0-2,05; марганец 0,6-0,8; медь 0,2-0,3; никель 0,5-0,9; хром 0,1-0,15; бор 0,02-0,03; кобальт 1,5-2,3; самарий 2,3-2,7; железо - остальное.The technical result is achieved in that the steel containing carbon, silicon, manganese, copper, nickel, chromium, boron, iron, additionally contains cobalt and samarium in the following ratio of components, wt.%: Carbon 2.0-2.05; silicon 2.0-2.05; manganese 0.6-0.8; copper 0.2-0.3; nickel 0.5-0.9; chrome 0.1-0.15; boron 0.02-0.03; cobalt 1.5-2.3; samarium 2.3-2.7; iron is the rest.

В таблице приведены составы стали.The table shows the compositions of steel.

Износ (потеря веса образца при трении с нагрузкой 150 кг) предложенной стали составит ~0,4×10-3 кг.Depreciation (weight loss of the sample during friction with a load of 150 kg) of the proposed steel will be ~ 0.4 × 10 -3 kg.

Марганец, медь, никель хром, бор, кобальт, самарий обеспечивают повышенную износостойкость сплава. Самарий, кобальт, медь, никель препятствуют возникновению и развитию трещин при трении. Медь, самарий препятствуют образованию задиров.Manganese, copper, nickel chromium, boron, cobalt, samarium provide increased wear resistance of the alloy. Samaria, cobalt, copper, nickel prevent the occurrence and development of cracks during friction. Copper, samarium prevent the formation of scoring.

Сталь может быть выплавлена в электропечах. Отливки подвергают нагреву до температуры 1100-1150°С и закалке в воде.Steel can be smelted in electric furnaces. The castings are heated to a temperature of 1100-1150 ° C and quenched in water.
