Low-temperature carbon steel A333
Thread Content
The minimum impact test temperature for low-temperature carbon steel A333GR.6 is -45 degrees. Is the minimum design temperature also -45 degrees?
The minimum design temperature is not applicable to the material itself, but rather to the equipment that uses that material; in other words, for equipment that utilizes this low-temperature material, the minimum operating temperature is -45°C.
A333 is the standard for seamless steel pipes; grade Gr6 requires a low-temperature impact test at -46 degrees upon leaving the factory, with the impact energy meeting the standard requirements. Wugang Panglong 13137747779
Not necessarily; the design temperature should be greater than or equal to -45℃
