What temperature is suitable for 304 stainless steel plate

Release time:2021.06.19 Announcer: Hits:

We all know that stainless steel is resistant to high temperature and corrosion, so at what temperature is 304 stainless steel suitable for use? The operating temperature of 304 stainless steel plate is 190~860 degrees Celsius, but in actual use, the operating temperature of 304 stainless steel plate is not as high as 860 degrees Celsius. Why does this happen? How can 304 stainless steel reach? What about temperature intensity?

In fact, the operating temperature of 304 stainless steel is not suitable to be maintained between 450 and 860 degrees Celsius. When the temperature of 304 stainless steel reaches 450 degrees, a critical point will appear. At this critical point, the stainless steel will dilute the chromium around the carbon element. Then the chromium carbide is formed, and the chromium-depleted area appears where the diluted chromium originally exists. The appearance of the chromium-depleted area will change the performance and material of the stainless steel. In addition, the temperature of 450 degrees Celsius and the yield force will make the austenite to the horse. Body transformation.

Generally speaking, 304 stainless steel has good acid resistance, and the concentration of nitric acid is within 70%. Temperature 0-80℃ and so on, stainless steel 304 material is one of the materials with very good alkali resistance, most of the alkali can be used in the range of 0-100℃.
