Q345 is a Chinese standard for low alloy structural steel, and it
is not classified as carbon steel. The correct designation for
carbon steel pipes in China is usually represented by the "G"
followed by the carbon content in the steel. For example, a common
carbon steel grade for pipes in China is GB/T 8163 10# steel, which
means it has a carbon content of about 0.10%.
