Causes of solution annealing treatment of stainless steel tubes

Stainless steel tube production needs to use a lot of technology, will also need some processing operations, through these can effectively improve their quality, so why does it need solution annealing treatment?The following reasons are needed for solution annealing:

1, make the stainless steel tube structure and composition uniform: this is especially important for raw materials, because the hot rolled wire sections of the rolling temperature and cold solidification speed is not the same, resulting in inconsistent structure.At high temperature, the atomic activity intensifies, the chemical composition tends to be uniform, and the uniform single-phase structure is obtained after rapid cold fixation.

2, clean up the work hardening, in order to facilitate the continued cold working: through the solution treatment, the distorted lattice recovery, elongation and broken grain recrystallization, internal stress elimination, the tensile strength of the steel pipe decreased, the elongation rate increased.

3, restore the inherent corrosion resistance of stainless steel: due to cold processing caused by carbide precipitation, lattice problem, the corrosion resistance of stainless steel decline.After solution treatment, the corrosion resistance of stainless steel tube recovered to a better state.

Therefore, from the performance of the stainless steel tube, quality and other perspectives, in order to be able to stabilize its performance, in the whole production and processing, the solution annealing treatment, these can be a great help to the performance of the product.
