What is the tempering treatment of stainless steel precision casting?

Stainless steel precision casting is an excellent technology in the casting industry, which is widely used, not only for various types and alloys. So do you know what the tempering treatment of stainless steel precision casting is?

 

According to the performance requirements of stainless steel precision casting, the tempering temperature is divided into low, medium and high.

 

The main results are as follows: 1. When the low temperature tempering temperature is 150 ~ 250 ℃, the microstructure obtained is the same fire martensite, that is, a part of carbon is precipitated from the supersaturated martensite and carbides are formed around the martensite.

 

2. The tempering temperature of medium temperature is 350 ~ 500 ℃, and the tempering structure is tempered troosite, which has good strength and toughness. This tempering process is widely used in low alloy cast steel.

 

3. The high temperature tempering temperature is 500 ~ 650 ℃, and the tempering structure is dispersed and granular sorbite. The quenching and tempering process is called quenching and tempering. It is suitable for low alloy steels with multi-component strong carbide forming elements and has high strength and toughness.

 

When we are all in stainless steel precision casting, the tempering treatment methods for stainless steel precision casting are mainly the above, and we can all deal with our stainless steel precision casting in accordance with the above treatment.
