What material should be chosen for a tower with a temperature of around 820 degrees?
Thread Content
I ran into a tough problem today – the boss wants to build a tower that can withstand temperatures of 820 degrees, and he’s asking me to choose the materials. This is really messing me up. 820 degrees – it’s said that some kind of pyrolysis gas needs to be introduced, but I don’t understand it. I’d appreciate advice from those who know more about this.
This generally requires internal thermal insulation and double lining; otherwise, the temperature of this material will be extremely high! Unless your boss has no money worries, go with stainless steel straight away!
That’s apparently how boilers work; this is something worth considering.
Thank you all. I’ve done some research, but I’m not sure if the following conclusions are correct Digital code New grade Old grade American standard code S31020 20Cr25Ni20 2Cr25Ni20 310 S31008 06Cr25Ni20 0Cr25Ni20 (1Cr25Ni20Si2) 310S S30908 06cr23Ni18 0Cr23Ni18 309 So the question is: how should the allowable stress be determined at such temperatures?
