The role of the stainless steel flange solution treatment
Solution treatment refers to the heat treatment process in which the alloy is heated to a high temperature single-phase zone to maintain the temperature,and the excess phase is fully dissolved in the solid solution and then rapidly cooled to obtain a supersaturated solid solution.The role of the stainless steel flange solution treatment:
Mainly to improve the plasticity and toughness of steel and alloy,and prepare for precipitation hardening treatment.
Make the structure and composition of stainless steel uniform: the atomic activity is intensified at high temperature, the σ phase is dissolved, the chemical composition tends to be uniform, and a uniform single-phase structure is obtained after rapid cooling.
The various phases in the alloy are fully dissolved,the solid solution is strengthened,the toughness and corrosion resistance are improved,and the stress and softening are eliminated to continue processing or molding.
Eliminate work hardening, in order to facilitate the continued cold processing. Through the Solution Treatment, the lattice recovery of the twist, the elongated and broken grains recrystallize, and the internal stress is eliminated.
Restore the inherent corrosion resistance of stainless steel. Due to the precipitation of carbides due to cold working, the lattice defects cause the corrosion resistance of the stainless steel to decrease. After the Solution Treatment, the corrosion resistance of the stainless steel is restored to a good condition.
