FAQs
While both are seamless carbon steel pipes, GR.C has a slightly higher carbon content, providing increased tensile strength and durability. This makes GR.C better suited for applications with high pressure and temperature requirements.
ASTM A53 GR.B is typically used for moderate temperature applications. For higher temperatures, ASTM A106 GR.B or GR.C would be more suitable.
ASTM A333 GR.6 is engineered to perform well at sub-zero temperatures, providing excellent impact resistance and preventing brittleness, which makes it ideal for cryogenic and low-temperature applications.
