When selecting stainless steel for high-temperature applications, the choice of which type to use is often determined by the specific requirements of the application and environmental conditions. However, generally speaking, the stainless steel types used for high-temperature applications can include the following:
1. AISI 310 or 310S: These types of stainless steels are suitable for high-temperature applications exceeding 1000°C. They are commonly used in heating elements, furnaces, and other equipment operating at high temperatures.
2. AISI 316H: This type of steel is used in applications requiring high-temperature and high corrosion resistance, particularly in chemical processes.
3. AISI 321: AISI 321 stainless steel is used in applications requiring high-temperature and oxidation resistance. It is preferred in places such as exhaust systems, industrial furnaces, and heat treatment ovens.
4. AISI 304H: This type of stainless steel can be used in applications requiring durability at high temperatures, especially in power plants, boilers, and petrochemical facilities.
The selection of stainless steel for use at high temperatures involves a range of factors, including temperature, corrosion effects, mechanical strength, and cost. Therefore, it is important to seek engineering evaluations and advice from material experts to choose the most suitable steel type for a specific application.
