Through some processing operations, it is not difficult to find that in fact, stainless steel castings are basically inseparable from the operation of heat treatment in various processing operations, but heat treatment is accompanied by high temperature, so the following matters need to be paid attention to in the process of heat treatment:
1. Stainless steel castings form a coarse grain structure during the casting process. Compared with forgings or rolled parts, long-term solution treatment and aging are required.
2. Because the solution treatment temperature is close to the melting point of the low-point eutectic, it is necessary to use a heating furnace with easy temperature control and an instrument with accurate temperature control.
3. Due to different chemical compositions, each series of aluminum alloys has different heat treatment characteristics and processes. Appropriate process parameters should be selected according to the chemical composition, structural characteristics, technical requirements and other factors of stainless steel castings.
When heat treatment, I hope that everyone can choose the appropriate process, and in the process of treatment, especially when heat treatment is required, the above matters should be paid attention to at this time, so as to benefit the quality of stainless steel castings.
