What is the maximum temperature resistance of 321 stainless steel?

SUS321 stainless steel high temperature resistance
SUS321 has good high temperature resistance and can be used for a long time in a high temperature environment of 600-700℃ without failure. Its maximum operating temperature is around 800℃, and its corrosion resistance is also excellent at lower temperatures. This makes SUS321 an ideal choice for many high temperature applications, such as petrochemical, aerospace, nuclear industry and heat treatment industry.

Chemical composition of SUS321 stainless steel
The chemical composition of SUS321 includes elements such as chromium, nickel and titanium. Among them, the content of chromium is 17-19%, the content of nickel is 9-12%, and the content of titanium is 5×C-0.7%. The addition of these elements makes SUS321 have excellent high temperature resistance and good corrosion resistance, especially in high temperature and oxidizing environments.

Characteristics of SUS321 stainless steel
SUS321 has many unique characteristics, such as good corrosion resistance, excellent high temperature resistance, stable chemical properties, good welding performance, easy processing and maintenance, etc. In addition, SUS321 also has good weldability and plasticity, and can be formed by cold working, hot working and other methods.

SUS321 stainless steel application field
SUS321 is widely used in high-temperature fields such as petrochemical, aerospace, nuclear industry and heat treatment industry.
