Bearing steel is what material

High temperature high temperature bearing steel material analysis of the rolling bearing in the bearing steel is mainly used to produce high temperature and the rolling ring. Because of the bearing should be with high temperature and short life, high precision, low calorific value, high speed, high rigidity, low noise, high abrasion resistance and other properties, so the high temperature bearing steel request should have: high hardness, the average hardness, high elastic limit, the contact fatigue strength and high toughness necessary, certain hardenability, smooth agent in atmosphere corrosion resistance. In order to achieve the performance requirements, chemical composition, types and nonmetallic inclusions, the size and distribution of carbide, decarbonization serious request the content of the average high temperature bearing steel. In order to high quality, high performance and many kinds of high temperature bearing steel overall direction. According to the application environment characteristics and high temperature bearing steel can be divided into: high temperature and high carbon chromium bearing steel, bearing steel carburizing temperature, high temperature and high temperature bearing steel, stainless steel and special high temperature bearing special high temperature bearing information. High temperature bearing steel type high temperature bearing steel mainly can be used for manufacturing high temperature bearing system and the development of the main parts and components, such as high temperature bearing of ball bearing, roller and high temperature bearing ring and other steel products. Living conditions due to the high temperature bearing research, economy rapidly developed, and the special need of scientific management technology from learning environment is becoming more and more with complex mechanical work, for example, shaft rotation speed requirements of more and more faster, bear the load of problem more and more heavy, the temperature changes in the working process of the more and more high, the high temperature bearing the force analysis of environmental protection is more and more important and complex ( In addition to the gravity, and more in the direction of thrust) All this, request all qualified for high temperature bearing, bearing according to the request of social stable operation. And high temperature bearing steels required in strength, rigidity and wear resistance, hardness, physical and mechanical properties of the average resistance and contact fatigue strength function, etc. These aspects can keep up with The Times and technology developed, and the progress from time to time. After research, it has control, progress the performance of the high temperature bearing steel meets all these requirements, necessary - smelting iron Carbon alloy steel ( Anaerobic) And then attend a certain number of carbon and chromium is very high, the purity of silicon, manganese, vanadium alloy, and accordingly, heat treatment, can get high temperature bearing steel with request. Our high temperature bearing steel can be roughly classified into four categories, and are listed as follows: 1. High temperature high carbon chromium bearing steel, level: GCr6; GCr9; GCr95s iMn 2。 Carburized high temperature chromium bearing steel grades: G20CrMo; G20CrNiMo； G20CrNi2Mo； 3. High carbon chromium stainless steel high temperature bearing steel, the brand name: cr4mo4f; 9cr18mo; As shown in figure 4, the high temperature of high temperature bearing steel, specify: Cr14Mo; 16 cr14mo do not contain the high temperature of chromium bearing steel, brand: GSiMnV; GSMVRE； GSiMnMoV, be able to replace chrome high temperature bearing steel. High temperature bearing steel hardness is a few? The hardness after heat treatment in generally between 30 and 50 high temperature bearing steel. High temperature of bearing steel structure high temperature bearing steel manufacturing, also known as high carbon chrome steel, carbon content about 1% c, omega omega cr chromium content is 0. 5% - 1. 65%. High temperature bearing steel is divided into high temperature high carbon chromium bearing steel, chromium high temperature bearing steel, carburized high temperature bearing steel, high temperature stainless bearing steel, high temperature in the high temperature bearing steels and anti high temperature magnetic bearing steel six categories.
