| description | The invention belongs to the technical field of metallurgical materials, and relates to a manufacturing method for controlling deformation of a ferrite/martensitic steel hexagonal pipe. The manufacturing method sequentially comprises the following steps of (1), carrying out hot extrusion; (2), rolling and annealing intermediate cold; (3), rolling a circular tube into a hexagonal tube; (4), normalizing and tempering an intermediate pipe; (5), carrying out cold rolling on finished product; (6), carrying out final heat treatment. By means of the manufacturing method for controlling deformation of the ferrite/martensitic steel hexagonal pipe, the obtained hexagonal pipe can meet the strict requirements of a fast reactor core assembly on the straightness, the wall thickness, the inner opposite side distance, the torsion resistance and the like of the ferrite/martensitic steel hexagonal pipe.
