Special Bearing Steel for Special Environment
Bearing steel is an important material for the manufacture of rolling bearings which are widely used in a variety of mechanical products. Due to its high mechanical properties, high fatigue strength and low noise, bearing steel is favored by many bearing manufacturers. However, for bearings used in special environments, traditional bearing steel may not be able to meet the requirements for use. Therefore, special bearing steel needs to be used to meet the performance requirements of use in special environments.
Special bearing steel refers to steel used for bearings in special environments, such as high temperature environment, high strength environment, corrosion and wear environment, etc. In the past, the main bearing steel used in the bearing industry was carbon steel, but with the development of technology, various alloy steels and stainless steels have been widely used.
For example, in a high-temperature environment, alloy steels that can resist high temperatures and stainless steels have been widely used, such as 42CrMoV, 50CrMoV and GB/T 10536-89 high-temperature bearing steels. In order to improve the corrosion resistance of bearings in a corrosive environment, stainless steel and surface corrosion prevention lubricant can be adopted. In addition, the new composite material, known as cementite, is also used in bearings in special environments, such as high temperature, high strength and corrosion resistance, to ensure that the performance of the bearings meets the requirements.
In short, special bearing steel is an indispensable material for bearing products in special environments. People have made a series of improvements on bearing steel materials in order to meet the requirements of use in different special environments. As technology continues to advance and bearing steel materials continue to improve, it will be more and more widely used in special environments.
