  • Austempering of the spring.
    For springs with smaller diameters or satisfactory hardenability, austempering can be used, which can not only reduce decentering, but also improve strong resistance. It is best to perform another tempering after austempering to increase the elastic limit. The tempering temperature is the same as the austempering temperature.
  • Deformation heat treatment.
    Thermomechanical heat treatment is a combination of steel deformation strengthening and heat treatment strengthening to further improve the strength and resistance of steel. Thermomechanical heat treatment is divided into high temperature, medium temperature and low temperature. High temperature deformation heat treatment is quenched immediately after deformation in a stable austenite state, or can be combined with forging or hot rolling, that is, quenched immediately after hot forming.
  • The loose treatment of the spring.
    If the spring is operated under external force for a long time, slight plastic deformation will occur due to the loosening of the stress. Especially for the spring operated at high temperature, the stress loosening phenomenon is more serious at high temperature, which reduces the accuracy of the spring. This is not the case for general fine springs. Allowed. Therefore, this type of spring should be loosened after quenching and tempering. Heat treatment process: pre-load the spring so that its deformation exceeds the deformation that may occur during operation of the spring. Then heat it at 20℃ higher than the operating temperature for 8~24h.
  • Shot peening.
    Shot peening is one of the most widely used methods to improve the appearance of springs. Springs require high appearance quality. Surface defects such as scratches, folds, and oxidative decarburization tend to become local and fatigue fracture sources of stress concentration during spring operation. If fine steel shots are used to spray the surface of the spring at a high speed and perform shot peening, it will not only improve the appearance of the spring, but also increase the strength of the appearance and make the appearance in a state of compressive stress, thereby increasing the fatigue strength and service life of the spring.
  • Low temperature carbonitriding.
    Regarding the coil spring, the combination of tempering and low-temperature carbonitriding (nitrocarburizing) technology can significantly improve the fatigue life and corrosion resistance of the spring.

However, the main difference between stainless steel hardware springs and ordinary springs in terms of elasticity depends on the material composition of the spring. This also determines the price difference of stainless steel hardware springs.
    The different elements added in the stainless steel hardware spring or the different element content in the material will affect the various properties of the stainless steel hardware spring. Stainless steel spring is based on iron, adding other elements, such as: carbon, chromium, nickel, manganese, nitrogen, copper, cobalt, etc., thereby increasing the steel, elasticity, high temperature resistance and other characteristics of stainless steel.

    The use of “chromium” in stainless steel hardware springs is very important. (Each type of stainless steel will add different content of chromium elements). We all know that stainless steel is corrosion-resistant and not easy to be oxidized. This is how chromium plays a role in stainless steel springs. The effect is achieved, because it can passivate the iron, so as to achieve the effect of anti-corrosion.
    The role of “carbon” in stainless steel springs is mainly to improve the strength and rigidity of stainless steel springs. However, in the use of carbon, the application of chromium must be considered, because carbon and chromium easily form chromium carbide, which affects the role of chromium in the stainless steel spring and reduces the corrosion resistance of the spring.
    The role of “manganese” in stainless steel springs is mainly to improve stability. It can reduce the critical quenching speed of stainless steel and achieve the high temperature resistance of stainless steel springs.
    The application of various elements in stainless steel springs has different effects. At the same time, when adding each element, the chemical reaction between the elements must also be considered in order to effectively improve the performance of the stainless steel spring.
