It is understood that there are more than 40,000 varieties and millions of fasteners of various forms and sizes in China and abroad, and their use occasions and environment are ever-changing. For example, the industrial profile parts are used as the connecting parts of the main unit and the components. Together with the main machine, they bear the basic performance of the main body and the basic functions of the components, and must be adapted to high temperatures. high pressure. Low temperature. shock. Corrosion, heavy load, alternating stress, anti-shear and anti-twist, etc. However, the probability of a fastener failure causing an accident is very high, so the materials used to make the fastener must be carefully selected in advance.
Many domestic fastener companies have suffered high customer claims due to product quality problems. It is true that many quality problems are caused by material failure. How to correctly select materials for fasteners has become one of the topics of increasing concern for fastener companies.
For the status quo and existing problems of China's fastener steel, China Machinery General Parts Industry Association Fastener Professional Association material consultant Shen Gong said: China is currently a major fastener production country, but also the world's first steel producing country However, the development and production of steel for fasteners started late. The specifications of cold heading steel are relatively small, which cannot meet the domestic demand and export demand of current fastener production. In the production and market circulation of cold heading steel, many steel grades in G3506, G3507, G4105 and ASTM in the US are also borrowed.
