The difference between stainless steel spring and carbon steel spring

Firstly, due to the different compositions of the two materials, the main disadvantage of carbon steel springs is that they are prone to rusting, especially when used in high temperature and humidity environments. However, rusting can corrode the metal structure of the material, causing it to deform and fracture easily. Therefore, if the product is not used in a good environment, stainless steel springs should be used as much as possible. Secondly, the difference between the two is that due to different production processes, the performance of the product also varies. The production process of carbon steel materials is to obtain the high hardness of the spring by quenching and tempering the low hardness base material, which leads to poor toughness and low service life of carbon steel materials. In practical applications, there may be a phenomenon of overall fracture of the spring, while stainless steel materials are made of low hardness. The hardness of the base material is obtained by rolling several times using a rolling mill to obtain the thickness and hardness required for producing the spring, At the same time, it also achieves good toughness, ultimately leading to a better service life and more stable performance than carbon steel springs
Finally, there is the price difference between the two, as the chromium content in stainless steel materials accounts for 16-18%, and the nickel content accounts for 6-8%, so the price is also 2-3 times more expensive than carbon steel. For the same specifications of springs, under the same processing cost, the price difference between the two will be about 2 times
