Heat treatment method for high strength steel thin-walled cylinder bodies provided with sealing heads

The invention discloses a heat treatment method for high strength steel thin-walled cylinder bodies with sealing heads, wherein the heat treatment method belongs to the technical field of heat treatment and is particularly suitable for solving the problem that the cylinder bodies deform when the high strength steel thin-walled cylinder bodies with the sealing heads are heat-treated. The heat treatment method is characterized in that each thin-walled cylinder body internally equipped with a thin-walled cylinder body sizing device is together loaded in a vacuum tempering furnace for vacuum sizing tempering, wherein the patent number of the thin-walled cylinder body sizing device is ZL200920259747.3; the quenching deformation of a workpiece can be eliminated effectively during the heat treatment process by utilizing phase transition superplasticity on the premise that the mechanical properties of workpiece materials are qualified and the hardness of the workpiece is uniform; when vacuum quenching and tempering a
