Equipment manufacturing industry. Driven by the professional support of cars, the steady addition of stainless steel rivet nut assets and the continuous increase of exports, the equipment industry has recovered for five consecutive months. According to the statistics of the National Bureau of Statistics, from January to November of the previous year, the added value of the equipment manufacturing industry increased by 10.7% year on year, with a year-on-year growth rate of 2.5 percentage points, 1 percentage point higher than that of all industries above the planned level. During this period, 9%, 9.3% and 11.2% were added respectively in the first, second and third quarters, and 13% were added in October of the previous year, which has increased for half a year in a row.
All stainless steel rivet nuts have the same characteristics, that is, the chromium content is more than 10.5%. As usual, there are only six types of steel related to the application field of construction organization. They are all rich in 17-22% chromium, and better steel grades are also rich in nickel. Molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance of the atmosphere containing chloride.
Research shows that the level of atmospheric erosion varies from region to region. In order to facilitate the analysis, it is proposed to divide the regions into four categories: villages, cities, industrial areas and coastal areas. The village is basically a pollution-free area. The population density in this area is low, as long as there is no pollution industry. The metropolis is a typical habitat, trade and light industry zone, where there is slight pollution, such as traffic pollution.
At present, there is a great development trend in the air conditioning industry, and stainless steel rivet nuts are increasingly used in this industry. The following are the advantages of stainless steel rivet nuts in air conditioning:

1. The stainless steel rivet nut can effectively deal with the problem of "yellow water" after years of wind and rain, and effectively eliminate problems such as faulty welding.
2. Handle the loose connection of flanging tapping (or self tapping screw), improve the reliability of connection, effectively reduce the noise caused by loose connection, make the grounding more reliable and reliable, and facilitate maintenance.
3. Improve consumption efficiency, reduce the number of workers, and reduce labor costs. (Because the stainless steel press rivet nut adopts the method of press group riveting, so that the single welding method can be completed at one time, which is not only efficient, but also can reduce the use of points.) 4. Reduce the use of factory land.



5. Save energy (stainless steel rivet nuts can reduce data by 20% instead of flanging tapping (or self tapping)).
