Solid solution heat treatment of stainless steel pipe means that the welded stainless steel pipe is heated to about 1050 ℃, the chromium-containing carbide (Cr23C6) in the steel is re-decomposed into Cr atoms and C atoms, and then the pipe is cooled rapidly, so that the chromium content in the poor Cr area reaches the average content, and finally, to improve the corrosion resistance and plasticity of the steel pipe, and reduce the hardness of the steel pipe.
