Introduction
The development of bearing materials and heat treatment has occupied an important position in the development of China’s bearing industry. It has become an important driving force for Chinas bearing industry to better meet market requirements and provide qualified products for customers. It has become an important means for Chinas bearing industry to improve its competitiveness. In the future, bearing materials and heat treatments are expected to have a greater development momentum and make greater contributions to Chinas bearing industry.
Development of Bearing Materials
At present, Chinas bearing materials mainly include 50Mn, 42CrMo, GCr15 and other materials. As China’s bearing industry develops, bearing materials have been adjusted and updated accordingly. According to the needs of foreign countries and domestic markets, two kinds of low-carbon chromium steel bearing materials were developed. They are 9Cr18Mo and 15Cr2Ni2Mo. These bearings not only meet the requirements of Chinas bearing industry for international standards, but can also withstand higher loads and running speeds, and have better corrosion resistance and anti-dimensional changes. With the development of the bearing industry, more superior bearing materials may be developed in the future.
Development of Heat Treatment
Heat treatment was an important part of bearing industry production process. The heat treatment of bearings aims to improve the performance of the bearings and make it more suitable for use. At present, there are three commonly used heat treatment processes of bearings. They are carburizing, quenching and tempering, and low temperature tempering. These three methods have their own characteristics and are suitable for different situations. In order to better meet the needs of bearing users, in the future, more methods of heat treatment may be developed to treat bearing materials.
Conclusion
With the development of the bearing industry, bearing materials and heat treatments are constantly evolving. It will provide a great impetus for Chinas bearing industry to meet the higher requirements of the contemporary market. In the future, it is expected to bring more development and contributions to Chinas bearing industry.
