The high-strength development trend of spring steel wire

1. The of spring steel wire in your country is not very long. Today fashionable of spring steel wire is economic and high end. The spring steel grades of foreign are rather complete. The mechanical properties, hardenability and fatigue performance can basically satisfy the produce and use requirements at this time. On one hand, we should give full play on the potential of spring steel wire. For instance, improve the production technology, carry out some adjust to the spring steel with new technology. Seek to improve the performance. On the other hand, be diligent to the new spring steel. The brand new spring steel wire has to be economic and better, so the spring created by it can receive by customers. The 2 main main factors influencing the spring's stress are resistances to fatigue and elasticity weakening. Which means this two factors have was crowned the theme of research and progression of high-strength spring steel wire.
2. The spring steel wire usually expressed by the steel of Si-Mn system, like 55SiMnVB, 55Si2Mn, 60Si2Mn and low-carbon spring steel which coded in recent years, such as 28MnSiB, 35MnSiVB. In our country even offers spring steel Cr-Mn system and Cr-V system, but As a result of resources, they are more expensive. We have high-strength spring steel 55SiMnVB which is shortage and expensive, and isn't conducive to industrial production. The low-carbon spring steel 35MnSiB is high-strength spring steel wire developed recently, which several advantages, and has a promising prospect.
3. The spring steel wire in the country keeping the pace while using world's development, develops towards the high-strength.
