Temperature range of LCB low-temperature carbon steel
Thread Content
I would like to ask what the maximum temperature for LCB low-temperature carbon steel is. Thank you
ASME B16.5 specifies that it cannot be used above 340°C.

The intermediate-temperature yield strength of carbon steel for low-temperature applications follows the same pattern as that of carbon steel not intended for low-temperature use, but its high-temperature long-term strength decreases slightly, likely due to the influence of grain size on high-temperature long-term strength. I think this is probably also why the standard allows only use of the medium-temperature range up to 340°C, rather than allowing temperatures up to 425°C like in the case of non-low-temperature carbon steels.
