How to select materials for high-temperature pressure vessels?
Thread Content
Pressure P=2.5, temperature T≤600℃; media: CO, CO2, H2, etc. How should the material be selected for designing this pressure vessel?
316H and 347H can resist high-temperature hydrogen damage; for even higher temperatures, high-chromium-nickel stainless steels such as 25-20 are required.
Thank you for the advice. Regarding how to select container plates that are not covered by GB150 standards, could we discuss this privately? My Feixin signal is 499713500
Chromomolybdenum steel, nickel-based materials. 316H has also been in use for many years under similar operating conditions.
If the temperature at 1# houangang remains at 600 degrees, stainless steel is still the better choice; considering heat resistance, stainless steel is superior. For temperatures below 550 degrees, Cr-Mo (14Cr1MoR) steel is sufficient
Could there be other hazards from using it at this temperature for a long time? One netizen said that after 3 years of use, the impact toughness **decreased**
