Heat treatment process of 304 austenitic stainless steel thin-wall part and application of heat treatment process

The invention discloses a heat treatment process of a 304 austenitic stainless steel thin-wall part and application of the heat treatment process, and relates to the technical field of heat treatment processes. The heat treatment process comprises the following steps: vacuum solution treatment: under a vacuum condition, firstly heating the 304 austenitic stainless steel thin-wall part to 650-700 DEG C and preserving heat for 90-150 minutes, then heating to 850-900 DEG C and preserving heat for 60-120 minutes, then heating to 1030-1100 DEG C and preserving heat for 120-180 minutes, and finally introducing nitrogen for cooling. The heat treatment process is used for heat treatment of 304 austenitic stainless steel thin-wall parts, and the parts are machined or not machined after heat treatment. According to the heat treatment technology, the mechanical property and corrosion resistance of the part are guaranteed, and meanwhile the acid pickling procedure is omitted. 本发明公开了一种304奥氏体不锈钢薄壁零件的热处理工艺及其应用，涉及热处理工艺技术领域。热
