Heat treatment method and purpose of stainless steel investment casting parts

Due to the different uses of different Investment Casting Stainless Steel Castings, there are many methods of heat treatment, which can be basically divided into two categories. Organizational structure changes.

A type of heat treatment procedure is mainly used to eliminate internal stress, which is caused by different cooling conditions and conditions during the casting process of silica sol stainless steel. The structure, strength and other mechanical properties are not significantly changed due to heat treatment.

For the second type of heat treatment, al Qaeda has undergone significant changes. The main purpose of softening annealing is to decompose carbides, reduce their hardness, and improve workability. For ductile iron, the purpose is to obtain more ferrite structure.

The main purpose of normalizing treatment is to obtain pearlite and sorbite to improve the mechanical properties of Stainless Steel Casting. Quenching treatment is mainly to obtain higher hardness or wear strength, and at the same time to very high surface wear characteristics. The surface hardening treatment is mainly to obtain a surface hardened layer and at the same time obtain a very high surface wear resistance. The main purpose of precipitation hardening is to obtain high strength without drastic changes in elongation.
