What is the difference between stainless steel 310 / 310S and 304 material?

The difference between stainless steel 310, 310S, and 304 materials

1. Chemical composition differences:
-Stainless steel 310: contains higher levels of chromium (24-26%) and nickel (19-22%), as well as small amounts of silicon and manganese.
-Stainless steel 310S: Similar to 310, but with more molybdenum added to improve corrosion resistance.
-Stainless steel 304: contains low chromium (18-20%) and nickel (8-10%), suitable for general use.

2. High temperature performance:
-Stainless steel 310 and 310S: designed for high temperature environments, with excellent high temperature resistance and oxidation resistance.
-Stainless steel 304: loses some corrosion resistance at high temperatures and is not suitable for use in high-temperature environments.

3. Corrosion resistance:
-Stainless steel 310 and 310S: They have strong corrosion resistance and are particularly suitable for acidic and alkaline environments.
-Stainless steel 304: It has good resistance to ordinary corrosive environments, but not as strong as the 310 series in terms of corrosion resistance.

4. Application areas:
-Stainless steel 310 and 310S: commonly used in industrial fields that require high temperature and corrosion resistance, such as high-temperature furnaces, refining equipment, and heat treatment devices.
-Stainless steel 304: mainly used for general purposes such as food processing, construction, decoration, etc., not suitable for use in high temperature or strong corrosive environments.

In summary, stainless steel 310 and 310S are suitable for high temperature and corrosive environments, while 304 is suitable for applications in general environments. When selecting materials, it is necessary to consider their chemical composition, properties, and application scenarios based on specific needs.
