company news about What is the effect of LSAW steel pipe solution treatment

　　1. Make the structure and composition of the LSAW steel pipe uniform, which is especially important for the raw materials, because the rolling temperature and cooling rate of each section of the LSAW steel pipe are different, resulting in inconsistent structure. At high temperatures, the atomic activity intensifies, dissolves, and the chemical composition tends to be uniform. After rapid cooling, a uniform single-phase structure is obtained.

　　2. Eliminate work hardening to facilitate continued cold working. Through solution treatment, the distorted crystal lattice is restored, the elongated and broken crystal grains are recrystallized, the internal stress is eliminated, the tensile strength of the steel wire is reduced, and the elongation rate is increased.
