    2.25 Cr-Mo to sustain 1150 F

    metengr, The service environment would be about 1100 F @ 50 psi and the process is typical thermal oxidation with NOx, CO, CO2, H2O. Increased oxidation is amongst my main concern in this reactor. Thanks guys, the info you've provided has helped me to make a good decision. I really appreciate it.

    2.25 Cr-Mo to sustain 1150 F

    MJcronin, I didn't consider 9Cr for this pressure vessel. This vessel will be installed in the US

    2.25 Cr-Mo to sustain 1150 F

    thanks davefitz, I'm not very familiar with the ASME code. From your reply I take that I can't go for 1.25 Cr-mo for this reactor. Perhaps I should just picked SS304 for this duty

    Please also advise on 1.25 Cr 0.5 Mo temperature resistance

    2.25 Cr-Mo to sustain 1150 F

    I'd like to specify a Cr-Mo reactor (8 ft diameter) which can potentially see 1150 F @ 50 psig. SO far various info I've found suggests we cannot go beyond 1050 F. Our internal pipe spec however says 2.25Cr-Mo is good up to 1200 F. Can gurus out there give me some advice?
