What is the use of stainless steel flange solution treatment
Posttime:2020.07.31 Views:1055
{The role of stainless steel flange solution treatment du]
1. Mainly to improve the plasticity and toughness of steel and alloy, and prepare for precipitation hardening treatment. dao
2. Make the stainless steel structure and composition uniform: the atomic activity intensifies at high temperature, the σ phase dissolves, the chemical composition tends to be uniform, and a uniform single-phase structure is obtained after rapid cooling.
3. Fully dissolve the various phases in the alloy, strengthen the solid solution, improve toughness and corrosion resistance, eliminate stress and soften, so as to continue processing or forming.
4. 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, and the internal stress is eliminated.
5. Restore the inherent corrosion resistance of stainless steel. The precipitation of carbides and lattice defects due to cold working reduce the corrosion resistance of stainless steel. The corrosion resistance of stainless steel is restored to the best state after solution treatment.
[Solid solution treatment] refers to the heat treatment process in which the alloy is heated to a high temperature single-phase zone and maintained at a constant temperature, so that the excess phase is fully dissolved in the solid solution and then rapidly cooled to obtain a supersaturated solid solution.
