In order to ensure the performance homogenization of GB/T 8162 Q345D seamless steel pipe for for structural purpose, we need to strictly control the annealing temperature, heat preservation time and cooling speed of GB/T 8162 Q345D seamless steel pipe for structural purpose.(1) Strictly control the annealing temperature of GB/T 8162 Q345D seamless steel pipe. (2) appropriate heat preservation time. If the holding time is too long, it will lead to uniformization of GB/T 8162 Q345D seamless steel pipe for structural purpose, which is not conducive to spheroidizing. (3) Accurately control the cooling rate. The cooling rate of the spheroidizing annealing does not affect the shape of the pearlite, but it determines the dispersion of carbides and thus determines the hardness after annealing.

The application of GB/T 8162 Q345D seamless steel pipe for structural purpose:
GB/T 8162 Q345D seamless steel pipes are used For manufacture of pipelines, vessels, equipment, pipe fittings and steel structures.
