【 Jiaxing bearing 】 The classification of bearing steel

Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and we learn the classification of the bearing steel. Jiaxing bearing classification of bearing steel, bearing steel and the scope of application of special wide, usually we put the bearing steel is divided into four categories: high carbon chromium bearing steel, carburized bearing steel, high temperature stainless bearing steel and bearing steel, which brand of high carbon chromium bearing steel GCr15 production and consumption is the largest. 1) High carbon chromium bearing steel is suitable for the inner and outer ring and rolling body, tempering hardness of HRC61 - 64. Brand GCr15, GCr15SiMn, etc. , required content of P, S in steel is not greater than zero. 025%, and limit the content of residual elements such as Ni, Cu, control the oxygen content in steel, 12 x10 - 6) %. Provisions of pickling macrostructure inspection; According to the requirements, the quenching fracture inspection; Provisions of non-metallic inclusions, microscopic pore, microstructure, carbide is not uniformity, decarburization depth inspection; Cooling heading and punching with upsetting test of steel. This kind of steel with electric furnace smelting, also called for smelting vacuum degassing treatment or other refining method. This kind of steel is suitable for manufacturing of bearing ring and rolling body. 2) Carburizing bearing steel is suitable for the bearing with shock and seismic requirements. Brand G20CrMo, G20CrNiMoG20CrN12Mo etc, belong to low carbon alloy steel. The smelting method, chemical composition, mechanical properties, macrostructure ( Acid leaching at low and tower hairline) , high power organizations ( Non-metallic inclusions, grain size and microstructure) Regulations, strict requirements, and for some steel frame by ultrasonic inspection, carries on the jominy test. More made bar, used for agricultural and other machinery and other departments. 3) Stainless bearing steel is suitable for stainless and atmospheric corrosion resistance of bearings and precision miniature bearing. Brand G95Cr18, G102Cr18Mo, etc. , for the high carbon high chromium markov shape steel, the chemical composition, hardness, low power and high power organizations have strict rules, require the use of electric arc furnace and the electroslag remelting ( Can use the vacuum induction furnace and vacuum induction furnace smelting and the electroslag remelting) Process production. Many used for bearing corrosion under the conditions of work. 4) Jiaxing bearing high temperature bearing steel is suitable for the working temperature> 200 ℃ high temperature bearing. Brand G8Cr4M04V, adopts the vacuum induction furnace and vacuum induction furnace smelting and the electroslag remelting method production, chemical composition, strictly limit the content of P, S, in particular, strict inspection is high, the macrostructure and decarburization depth. Much work of bearings used in high temperature conditions. 5) Special bearing materials are suitable for magnetically bearings and special medium resistance to corrosion, such as G52 alloy, G60 will be alloy and self lubricating graphite steel, etc. If you are interested in the above jiaxing bearing factory introduction of HRB bearing or have any questions, please click on contact us page on the right side of the online customer service, or call: 4006578186, jiaxing bearing retail center you full thoughtful procurement consultant. - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
