Precision seamless steel pipe is a kind of steel with high elasticity. In application, especially in large-scale buildings, precision seamless steel pipe is used in most places with high elastic requirements. Why is the elasticity of precision seamless steel pipe so good? The reason is that a lot of elements are added in it.
The manganese steel plate which requires elasticity can be considered as "Mn series" or "SIMN series" spring steels, which belong to special alloy steels. Both 65Mn and 60Si2Mn can be used as selective materials. It can be used in the cold forming process of steel tube with large cross-section.
However, for the parts with small cross-section made of two materials, the cold drawing process is required to be above 500 ℃ and the tempering process is required to be above 200 ℃. And need the appropriate molding equipment and perfect process specification, ordinary heating can not achieve the effect.
