Stainless Steel Compression Springs are widely used in many industrial fields, and different manufacturing processes have a significant impact on their quality.
Cold rolling process is a common one. During the cold rolling process, the material is bent into a spring shape at room temperature. The advantage of this process is that it can better maintain the original performance of the stainless steel material, because without high temperature treatment, the material's structure will not change significantly due to thermal effects. Cold-rolled Stainless Steel Compression Springs have high dimensional accuracy, which is very beneficial for some application scenarios with strict requirements on the outer diameter, inner diameter and free height of the spring. For example, in precision instruments, cold-rolled springs can more accurately meet the design requirements and ensure the normal operation of the instrument. At the same time, the residual stress generated by the cold rolling process is relatively small, which helps to improve the fatigue life of the spring and reduce the risk of fracture caused by stress concentration during long-term compression and relaxation.
The hot rolling process is suitable for the manufacture of stainless steel springs with larger wire diameters. During hot rolling, the stainless steel material is heated to a high temperature, making it easier to shape. The hot coiling process can release the stress inside the material to a certain extent. For large springs, it can effectively avoid the problem of sudden deformation during use due to excessive internal stress. However, the hot coiling process may form a layer of oxide skin on the surface of the spring. If it is not handled properly, it will affect the surface quality of the spring and reduce its corrosion resistance. Moreover, temperature control during hot processing is crucial to the quality of the spring. Too high or too low temperature may cause changes in material properties and affect the elasticity and strength of the spring.
Whether it is cold coiling or hot coiling, subsequent processing procedures also play an important role in quality. For example, heat treatment can further adjust the hardness and elasticity of the spring, and surface treatment can enhance its corrosion resistance. In actual production, it is necessary to select a suitable manufacturing process according to the specific specifications and use requirements of Stainless Steel Compression Springs, and strictly control each link to ensure the production of high-quality products.
