Изобретение относитс  к изысканию сталей дл  изготовлени  подшипников качени , работающих при температуре до 480°С без смазки или с незначительной смазкой.The invention relates to the search for steels for the manufacture of rolling bearings operating at temperatures up to 480 ° C without lubrication or with little lubrication.

Известна сталь, содержаща  углерод, хром, молибден; ванадий и железо.Known steel containing carbon, chromium, molybdenum; vanadium and iron.

Цель изобретени  - повышение теплопрочностй и коррозионной стойкости.The purpose of the invention is to increase the heat resistance and corrosion resistance.

Предлагаема  сталь отличаетс  от известной тем, что .комлоненты вз ты при следующем соотношении, %:The proposed steel is different from that known for the fact that the components are taken in the following ratio,%:

1,3 -1,41.3 -1.4

14,5-16,5 4,0 -4,5 3,0 -3,5 до 0,3 до 0,3. остальное14.5-16.5 4.0 -4.5 3.0 -3.5 to 0.3 to 0.3. rest

Механические свойства данной стали после отпуска 600° С в течение 1 час следующие: Твердость, HRC54The mechanical properties of this steel after tempering 600 ° C for 1 hour are as follows: Hardness, HRC54

Коррозионна  стойкость (при 40°, влажность 98% в течение 60 сут), ,015.Corrosion resistance (at 40 °, humidity 98% for 60 days),, 015.
