. Bearing steel is divided into six categories: high carbon chromium bearing steel, chromium-free bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and antimagnetic bearing steel. High carbon chromium bearing steel
is the most produced bearing steel in the world. The carbon content
is about %
and the chromium content
is about .%

Since its birth in 2010
The main ingredients have basically remained unchanged over the years. With the advancement of science and technology, research work continues and product quality continues to improve. It accounts for more than % of the world's total bearing steel production
. So that if there is no special instructions for bearing steel, it means
. The main steel grades of high-carbon chromium stainless bearing steel produced in my country are
the main steel grades of carburized bearing steel are
the main steel grades of chromium bearing steel are

:-:..>.:#>The physical properties of bearing steel are mainly based on examining the microstructure, decarburized layer, non-metallic inclusions, and low-magnification structure. Generally, they are delivered by hot-rolled annealing and cold-drawn annealing. The delivery status should be stated in the contract. The low-magnification structure of steel must be free of shrinkage cavities, subcutaneous bubbles, white spots and microscopic pores. The center porosity and general porosity shall not exceed
grade. Segregation shall not exceed
grade. The annealed structure of the steel should be uniformly distributed fine-grained pearlite. The depth of decarburization layer, non-metallic inclusions and carbide unevenness should comply with the relevant national standards.
:-:..>.:#>The basic machinery casting industry such as precision bearings has become a key development industry during the 12th Five-Year Plan period. In order to achieve the economic growth goals proposed by the two sessions, urban infrastructure construction projects in various regions have started intensively. Bearing steel Market demand will also be released accordingly. With the sustained and rapid development of the bearing manufacturing industry, the prospects of the bearing steel market are promising. Domestic bearing steel manufacturers are actively developing new varieties of bearing steel. The development of the bearing manufacturing industry based on high-end products is the main trend in the future. In order to achieve the economic growth goals proposed by the two sessions, urban infrastructure construction projects have started in various places. The intensive construction of major engineering projects such as railways, affordable housing, water conservancy, ports, and airports has driven the recovery of the construction machinery manufacturing industry and boosted the demand for construction machinery bearings. Steel market demand has also been released. At the same time, the market prices of steel raw materials such as iron ore, coke, and high chromium continue to run at high levels, causing the production cost of bearing steel to continue to rise. The promotion of rigid costs has prompted an increase in the ex-factory price of steel plants, which has further driven the increase in the market price of bearing steel. These two favorable factors are stable. The growth spurred domestic demand. Industry insight research data "
In-depth Research Report on China's Bearing Steel Industry" shows that the current strong development momentum of the domestic bearing manufacturing industry will have a positive effect on the steady improvement of the bearing steel market. The demand for a number of high-end bearings has increased significantly, such as aerospace bearings, high-speed precision bearings for machine tool spindles, high-speed electric spindle bearings, precision bearings for machine tools in the photovoltaic industry, high-speed rail bearings, automotive bearings, pulley bearings for cranes, etc.
