Demand for high-strength fasteners for cars needs to be met

According to Xu Changming, director of the Information Resource Development Department of the National Information Center, in the first four months of this year, China's auto market has experienced a marked turnaround and the demand growth rate has dropped significantly, which is significantly lower than the current potential growth rate (17% to 18%). . From the monthly distribution, in the first four months of this year, the growth rate of demand for passenger cars dropped rapidly compared with the same period last year, only 3.4% in April, far below the 22.4% in January.

At present, domestic companies such as Baosteel have been optimistic about this market and are committed to developing steel products that meet the performance requirements of high-strength fasteners for automobiles.

He believes that this kind of change is formed by the superposition of a variety of unfavorable factors. If macroeconomic policies continue to maintain their current strength, it is very difficult for car demand growth to return to the level of long-term potential growth.

Xu Changming stated that it is expected that the auto market will recover to a growth level of around 10% in the 8 months after this year, and the total annual demand may be close to 20 million. In the next 10 years, the potential growth rate of passenger vehicles will be around 15%, and the trend will be high before and after.

Commercial vehicles will maintain a long-term growth trend of around 9% by 2020, slightly lower than the average annual growth rate of 13.2% between 1999 and 2009. This is because, before 2020, China is still in the stage of simultaneous acceleration of industrialization and urbanization. The average annual growth rate of GDP is about 9%. Due to the uneven distribution of resources in China, the transportation intensity is still high, and the share borne by roads is basically stable. Or slightly increase.

At the summit forum of the steel and machinery basic parts industry chain held on May 23, industry insiders said that the current slowdown in the automotive industry will affect the total demand for automotive fasteners, but some automotive high-end fasteners still have to import. Due to the impact of the Japan earthquake, some high-end automotive fasteners are in short supply. Related companies should seize the market and work with steel companies to develop products that meet the performance requirements of high-strength fasteners for automobiles.

According to insiders, the automobile is an equipment type product. Fasteners are one of the key parts of automobiles. The average amount of fasteners for passenger cars (whole vehicles) is about 37 kg.

The domestic supply of high-strength fasteners for cars in China is less than 25%, and most of them are purchased from abroad. The commonly used cold crucible steels include quenched and tempered alloy steels, low temperature tempered alloy structural steels, low carbon and low alloyed high strength steels, and ferritic-martensitic two-way steels. The alloy non-quenched and tempered steels are involved in ups and downs. For medium- and high-carbon steel for rods, medium-carbon steel for half shafts, medium-low-carbon steel for front axles, etc.
