S690QL steel plate spec annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S690QL steel plate spec annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S690QL steel plate spec annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate S690QL steel plate spec for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 S690QL steel plate spec and priming gray oxide primer, and arrange shipment in time.
