Abstract
The invention relates to an alloy steel for manufacturing bearings. The alloy steel is characterized by comprising the following components in parts by weight: 0.22-0.29 part of molybdenum, 0.36-0.45 part of carbon, 0.44-0.80 part of manganese, less than 0.33 part of copper, 0.16-0.23 part of silicon, less than 0.05 part of sulfur, less than 0.03 part of phosphorus, less than 0.25 part of chromium, less than 0.25 part of nickel, less than 0.3 parts of unavoidable impurities and the balance of iron. The alloy steel provided by the invention has higher strength, is good in wear resistance, excellent in cold deformation shaping and good in surface wear resistance, and improves the whole quality and service life of the bearing product, thereby effectively improving the continuous operation time of equipment, lengthening the maintenance period of the equipment, and reducing the use cost of the equipment.
Description
Technical field
The present invention relates to a kind of steel alloy for the manufacture of bearing.
Background technology
The steel alloy history of existing more than 100 year, the industrial alloy steel products that more uses is approximately in latter half in 19th century, at that time because turnout and the usage quantity of steel constantly increase, machinery manufacturing industry need to solve the processing problem of cutting of steel, the self-hardening steel that composition is 2.5%Mn-7%W has been invented by forces of Britain in 1868 uncommon special (R.F.Mushet), and cutting speed is brought up to 5 ms/min.Along with the development of business and transport, 1870 have built span at chromium steel for the U.S. (1.5～2.0%Cr) on Mississippi is the bridge of 158.5 meters; Difficulty occurs during due to tool member, and after a while, some industrial countries use nickel steel (3.5%Ni) instead and build the bridge of large span.Meanwhile, some countries are also used for nickel steel to build warship.Along with the development of engineering, require to accelerate mechanical velocity of rotation, within 1901, there is high carbon chromium roller bearing steel in West Europe.Within 1910, develop again the rapid tool steel of 18W-4Cr-1V type, further cutting speed has been brought up to 30 ms/min.The appearance of visible steel alloy and development, be the requirement that has adapted to social productive forces development, particularly inseparable with the needs of machinofacture, communications and transportation and war industry.
Bearing metal steel, belongs to high-carbon type steel alloy, and current bearing metal steel hardness is large, and wear resistance is strong, but be exactly under particular surroundings wear resisting property can change, do not reach the demand of equipment work, also there is in addition the poor shortcoming of erosion resistance.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of the steel alloy for the manufacture of bearing.
Described a kind of steel alloy for the manufacture of bearing, is characterized in that comprising the component of following weight percent: molybdenum 0.22-0.29; Carbon: 0.36-0.45; Manganese: 0.44-0.80; Copper: be less than 0.33; Silicon: 0.16-0.23; Sulphur: be less than 0.05; Phosphorus: be less than 0.03; Chromium: be less than 0.25; Nickel: be less than 0.25; Inevitably impurity is less than 0.3; Surplus is iron.
Described a kind of steel alloy for the manufacture of bearing, is characterized in that comprising the component of following weight percent: molybdenum 0.24-0.27; Carbon: 0.38-0.43; Manganese: 0.50-0.70; Copper: be less than 0.30; Silicon: 0.18-0.21; Sulphur: be less than 0.045; Phosphorus: be less than 0.025; Chromium: be less than 0.20; Nickel: be less than 0.20; Inevitably impurity is less than 0.3; Surplus is iron.
The present invention has higher intensity and wear resistance, and cold deformation is moulding good, and surface abrasion resistance is good, total quality and the work-ing life of bearing products are improved, thereby effectively improve the continuous operations time of equipment, the maintenance intervals of extension device, the use cost of having saved equipment.
