FAG bearing steel production is the main raw material of steel FAG Bearings , FAG Bearings FAG Bearings chrome steel into steel and chrome FAG bearing steel. FAG bearing rings manufactured pipe production use . FAG bearing steel pipe for the high dimensional accuracy , multi-use two , three-roll cross rolling extension machine ( see pipe Oblique Rolling ) hot-rolled production specifications subject to smaller cold-rolled, cold drawing production . With a long single piece of forged steel instead of turning round to produce or FAG bearing sets, saving metal , simplifying the manufacturing process and FAG Bearings FAG Bearings reduce costs .
Commonly used in pipe production and processing performance characteristics chromium 1.30% ~ 1.65% FAG bearing steel are as follows:
    ( 1 ) plastic ( perforation performance ) . FAG bearing steel has good ductility at high temperatures and piercing performance, but the heating temperature is not too high, the general control about 1150 ℃, high temperature prone to grain growth ( overheating ) , lower perforated metal performance.
    ( 2 ) thermal conductivity. FAG Bearings thermal conductivity than the low carbon steel is slightly lower , the tail should be properly controlled oven temperature ( especially when heated large section FAG bearing steel billet ) .
    ( 3 ) mechanical properties. FAG Bearings room temperature tensile strength than steel, carbon steel containing C0.3% is much higher ( about double ) , and high hardness , when cold deformation more difficult, and therefore to be in front of the ball cold deformation annealing to improve the plasticity and reduce the hardness to a difference of more than 1000 ℃ very much. FAG Bearings not have much difficulty hot-rolled steel .
    ( 4 ) the deformation resistance . FAG bearing steel with high deformation resistance ( see metal deformation resistance ) and greater sensitivity to temperature , the higher the temperature , the lower the resistance to deformation . Hot-rolled steel to prevent FAG rolling bearing cold steel . FAG bearing steel production is sometimes restricted sizing mill and straightening machine capabilities , it is because FAG Bearings pipe wall thickness , coupled with high deformation resistance at low temperatures , making the rolling force and straightening force increased significantly. Cold drawn steel pipe system FAG Bearings pulling force when pulling system than about 50% of high carbon steel .
    ( 5 ) wide exhibition . Approximately 10% to 20% of the big wide exhibition FAG bearing steel than carbon steel , but within a temperature range of 885 ~ 1195 ℃ little change , which controls the production of the metal to bring the convenience of lateral deformation .
    (6) FAG Bearing Steel cooling. After cooling the hot-rolled steel should make FAG Bearings with good microstructure, ie fine lamellar pearlite and no mesh carbide precipitation . Such organizations can create the conditions for obtaining fine pearlite after FAG spherical bearing steel ball annealing . FAG Bearings time due to the chromium hot-rolled steel is cooled to 850 ~ 900 ℃ began to have a lot of carbide precipitation and reticular distribution , so the final rolling temperature should be controlled above 850 ℃, and take rapid cooling to prevent carbide precipitation . In order to achieve rapid cooling , fan or spray device generally set in a cold bed or cooling bed at the input roller .

FAG bearing chrome steel mesh available qualified carbide grade hot under normal conditions. Drawing the tube end before the hammer hammer after heating and cooling the same to prevent carbide precipitation.
     (7) FAG bearing steel life. Development of industrial machinery and vehicles for FAG bearings, made ??of high load and speed requirements, so FAG bearing life received special attention. Before new developed FAG higher life bearing steel, bearing steel, the primary way to improve the life of the FAG to improve the purity of the steel, the steel because even small amounts of oxides, sulfides, nitrides will greatly reduce the use of inclusions life. This requires FAG bearing steel smelting should adopt various means to reduce inclusions, in order to reduce inclusions, use more advanced FAG bearing steel electroslag remelting method to get the tube.
     FAG Bearing Steel Materials Research is constantly moving forward in the future more FAG bearing steel material will be developed by that time will be able to produce higher performance FAG bearing product.
