How much do you know about investment casting heat treatment?

1. The organizational structure will not change or should not change due to heat treatment, 2. Basic changes in the organizational structure.

Therefore, regarding the 2 types of heat treatment, it can be roughly divided into 5 categories:

1. Surface hardening treatment to obtain a surface hardened layer can also obtain higher surface wear resistance.

2. Quenching treatment to obtain higher hardness or wear strength and higher surface wear resistance.

3. Precipitation hardening treatment to obtain high strength without drastic changes in elongation.

4. Obtain pearlite and sorbite structures and improve the mechanical properties of stainless steel casting.

5. Soft annealing used to decompose carbides can improve processing performance and obtain more ferrite structure.


Compared with the traditional sand casting process, the castings obtained by precision casting have more accurate dimensions and better surface finish. Precision casting is widely used. The development trend of this process in the future is that the casting products are getting closer and closer to the part products. The parts products produced now It is becoming more and more complex, the quality level is getting higher and higher, the research and development methods are getting stronger and stronger, and professional cooperation is beginning to appear.

Precision casting products are more precise. The structure is also more complex and is close to the shape of the part. It is a relatively advanced process and is widely used. It is suitable for various types. It casts various alloys and produces castings with dimensional accuracy. The surface quality is much higher than other Casting method, other casting methods are difficult to withstand high temperature casting. Castings that are complex and difficult to process can be precision casting. At present, precision casting technology has been widely used in various industries, and the future development prospects are very broad.
