  • Telfon stud bolts are generally collectively referred to as "non-stick coating"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used as a way of lubrication, and it has also become an ideal coating for non-stick pots and water pipes.

    It is widely used as high and low temperature resistant, corrosion resistant material and insulation in nuclear energy, national defense, aerospace, electronics, electrical, chemical, machinery, instrument, meter, construction, textile, metal surface treatment, pharmaceutical, medical, food, metallurgy and smelting industries Materials, anti-stick coatings, etc., make it an irreplaceable product.
    Telfon stud bolts has fierce competition in the market and is moving towards brand management. In the past 10 years, China's bolts have attracted the attention of the world at the speed of development, which has surprised developed countries, but also allowed them to discover a new type of large market where multinational companies have entered. When domestic bolt companies suddenly felt that it was so difficult to survive in the market, strong competitors have blossomed everywhere.https://www.ydfastener.com/product/telfon-stud-bolts/

  • Heavy hex bolts are made of high-strength steel, or bolts that require a large pre-tightening force, can be called high-strength bolts. High-strength bolts are mostly used for the connection of bridges, steel rails, high-pressure and ultra-high pressure equipment. The fracture of this kind of bolt is mostly brittle fracture. High-strength bolts applied to ultra-high pressure equipment need to be pre-stressed in order to ensure the sealing of the container.
    Today, advanced manufacturing represented by large aircraft, large power generation equipment, automobiles, high-speed trains, large ships, and large complete sets of equipment has entered an important development direction. As a result, fasteners will enter an important stage of development. High-strength bolts are used for the connection of important machinery. Repeated disassembly or various installation torque methods require extremely high-strength bolts.
     Therefore, the surface condition and thread accuracy will directly affect the service life and safety of the host. In order to improve the coefficient of friction and avoid corrosion, seizure or jamming during use, the technical requirements stipulate that the surface should be treated with nickel-phosphorus plating. The thickness of the coating is guaranteed to be within the range of 0.02~0.03mm, and the coating is uniform, dense and without pinholes.
    Heavy hex bolts must be quenched and tempered according to technical requirements. Heat treatment and tempering is to improve the comprehensive mechanical properties of fasteners to meet the specified tensile strength value and yield ratio of the product. The heat treatment process has a vital influence on high-strength fasteners, especially its internal quality. Therefore, to produce high-quality high-strength fasteners, advanced heat treatment technology and equipment are necessary.https://www.ydfastener.com/product/bolts/
