Abstract
The invention relates to an alloy steel formula for bearings, which is characterized by comprising the following components by weight percent: 3.4-4.8% of titanium, 0.36-0.45% of carbon, 0.04-0.05% of magnesium, 0.32-0.39% of zirconium, 0.16-0.37% of silicon, 0.23-0.29% of molybdenum, 0.45-0.80% of manganese, less than 0.04% of sulfur, less than 0.05% of phosphorus, less than or equal to 0.25% of chromium, less than 0.25% of nickel, less than 0.25% of copper, less than 0.1% of inevitable impurity, and the balance of iron. According to the invention, higher strength and abrasion resistance are achieved, the cold deformation shaping is good, the surface abrasion resistance is good, and the overall quality and service life of the bearing product are improved, so that the continuous operation time of equipment is effectively increased, the maintenance period of the equipment is prolonged, and the use cost of the equipment is reduced.
Description
Technical field
The present invention relates to a kind of bearing fills a prescription with steel alloy.
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, turnout and usage quantity due to steel constantly increased at that time, 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 Britain forces in 1868 uncommon special (R.F.Mushet), and cutting speed is brought up to 5 ms/min.Along with the development of business and transportation, 1870 Nian for the U.S. chromium steel (1.5～2.0%Cr) on Mississippi, to have built span be the bridge of 158.5 meters; Difficulty occurs during due to tool member, and after a while, some industrial countries use the bridge that nickel steel (3.5%Ni) is built large span instead.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, in West Europe, there is high carbon chromium roller bearing steel.Within 1910, developed 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 wear resisting property under particular surroundings, can change, and does not reach the demand of equipment work, also has 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 the technical scheme of steel alloy formula for a kind of bearing.
Described a kind of bearing steel alloy formula, is characterized in that comprising the component of following weight percent: titanium: 3.4-4.8; Carbon: 0.36-0.45; Magnesium: 0.04-0.05; Zirconium 0.32-0.39; Silicon: 0.16-0.37; Molybdenum 0.23-0.29; Manganese: 0.45-0.80; Sulphur: be less than 0.04; Phosphorus: be less than 0.05; Chromium: be less than or equal to 0.25; Nickel: be less than 0.25; Copper: be less than 0.25; Inevitable impurity: be less than 0.1; Surplus is iron.
Described a kind of bearing steel alloy formula, is characterized in that comprising the component of following weight percent: titanium: 3.8-4.4; Carbon: 0.38-0.43; Magnesium: 0.042-0.048; Zirconium 0.34-0.37; Silicon: 0.20-0.33; Molybdenum 0.24-0.28; Manganese: 0.55-0.70; Sulphur: be less than 0.38; Phosphorus: be less than 0.045; Chromium: be less than or equal to 0.20; Nickel: be less than 0.20; Copper: be less than 0.20; Inevitable impurity: be less than 0.1; 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 have been improved, thereby effectively improved the continuous operations time of equipment, the maintenance intervals of extension device, the use cost of having saved equipment.
