Vessel Heads

The reason for the heat treatment of the cold-pressed and spun-sealed heads is: after cold-pressure deformation (spinning is also carried out in a cold state), the hardness and strength of the head are increased, the ductility and toughness are lowered, and work hardening occurs. Heat treatment can eliminate this phenomenon, improve the plasticity, toughness and hardness of the material. Heating and heat treatment are not the same thing, but in the case of thermoforming, the residual heat after molding has a heat treatment effect, so that the head after hot pressing generally does not need to be further heat treated.
