The Working Principle and Materials of Precision Stainless Steel Spring
Precision stainless steel springs are widely used for damping and energy storage in many fields such as automobiles, electrical appliances, and aircrafts. An external load is applied to the spring, and the spring vibrates to generate a force opposite to the original force, so as to reduce the impact of the external force, thus achieving the purpose of controlling the vibration and improving the overall stability of the system. This article will introduce the working principle and materials of precision stainless steel spring.
The operating principle of the precision stainless steel spring is very simple. When the external force is applied to the spring, the spring deforms, and the deformation of the spring can store a certain amount of mechanical energy. When the external force is released, the stored mechanical energy is released in the form of an oscillation, which can effectively prevent the system from vibrating or undulating because of any external force or instability. In addition, due to its good elasticity, precision stainless steel springs play an important role in controlling mechanical movement, adjusting the operation accuracy of various components, and other mechanical applications.
The materials used in precision stainless steel springs need to meet high requirements for mechanical properties, corrosion resistance and heat resistance. Generally, the following materials are used for the production of precision stainless steel springs.
High carbon chromium stainless steel is the most commonly used spring material, of which high carbon chromium stainless steel (17Cr-7Ni-3Si-3Mo-1Ti) is usually used as the material for precise cold-rolled forming. It has high strength, good hardness and elasticity, high fatigue strength and corrosion resistance. It is suitable for applications that require improved performance and a longer life.
Inconel 718 is a nickel-based superalloy with high strength, good surface stability and oxidation resistance, as well as good wear resistance, fatigue strength and corrosion resistance. Nickel-based superalloys are best suited for springs used in hot and high-pressure applications.
MP157 is a heat-treatable, boron steel heat-treated spring material. This material has excellent strength after hardening and tempering, but its strength and plasticity are poor in annealing state. Therefore, it needs to be heat-treated to form the required characteristics.
The above three kinds of materials are widely used in the production of precision stainless steel springs. Although provides a broad range of materials, the most suitable spring material should still be selected according to the requirements of the spring application and its working environment.
In conclusion, precision stainless steel springs can effectively control mechanical movement and improve the accuracy of operation of various components. High carbon chromium stainless steel, Inconel 718 and MP157 are commonly used materials for the production of precision stainless steel springs. The selection of the appropriate material should be based on the application and working environment of the springs.
