What temperature is suitable for 304 antibacterial stainless steel plate?

We all know that antibacterial stainless steel material is resistant to high temperature and corrosion, so at what temperature is 304 antibacterial stainless steel plate suitable for use? The use temperature of 304 antibacterial stainless steel plate is 190~860 degrees Celsius, but in actual use, 304 antibacterial stainless steel The service temperature of the plate is not as high as 860 degrees Celsius. Why does this happen? What kind of temperature strength can 304 antibacterial stainless steel achieve?

In fact, the use temperature of 304 antibacterial stainless steel is not suitable to be maintained between 450 and 860 degrees Celsius. When the temperature of 304 antibacterial 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. Element, and then form chromium carbide. The chromium-depleted area appears where the diluted chromium originally exists. The appearance of chromium-depleted area will change the performance material of antibacterial stainless steel. In addition, the temperature of 450 degrees Celsius plus the yield force will make austenitic The body transforms to martensite.

304 antibacterial stainless steel This kind of stainless steel generally has better acid resistance, and the nitric acid concentration is within 70%. Temperature 0-80℃ and so on. Antibacterial stainless steel 304 material is one of the materials with very good alkali resistance. Most alkalis can be used in the range of 0-100℃.
