I would like to ask about the operating temperature for steel
Thread Content
Could the experts tell me where I can find the upper and lower limits for the operating temperature of steel? The company is designing a dust collector with flue gas temperatures of 650°C; what material would be suitable for use, 304? 201? 430?
http://www.csres.com/ This is the website of the Industrial Standards Network. You didn’t mention where the steel will be used or what it’s for; you should check and search on your own. However, accessing these standards requires payment.
There is a book on metal materials that provides a detailed explanation; you can look it up
GB150-1998 (2003 revision) Steel Pressure Vessels – Material Section: Mechanical properties of materials, chemical properties, temperature usage limits
The chemical engineering design manual covers this in detail, with specific sections on material selection
Yours should be a pressure vessel; in Chapter 4 of GB150, the table of allowable stress values for materials specifies the maximum operating temperature for those materials. 0Cr18Ni9 can be used at up to 700 degrees, but its allowable stress is quite low
Dust collector; flue gas temperature of 650°C, 304H material used
It’s also included in the pressure pipeline training manual
If insulation is possible, it’s best to insulate the wall temperature; otherwise, the material needs to have good high-temperature performance
