The chemical composition of Q195 seamless steel pipe mainly includes C, Si, Mn, P and S. The content of C is ≤0.12%, Si≤0.30%, Mn≤0.50%, P≤0.035% and S≤0.040%.
The chemical composition of Q235 carbon steel pipe contains C content ≤ 0.22%, Si ≤ 0.35%, Mn ≤ 1.40%, P ≤ 0.045%, S ≤ 0.050%.
Q195 seamless carbon steel pipe has high tensile strength and yield strength, as well as good plasticity and elongation, which makes it perform well when bearing large loads. Its tensile strength is 390MPa and its elongation is 30%.
The tensile strength of Q235 carbon steel seamless pipe is higher, 490MPa, but its elongation is slightly lower, 23%.

Carbon Steel Q195 Q235 Tube
Application of Carbon steel pipe zinc coated q195 q235
The temperature resistance range of Q195 steel pipe is generally between -20°C and 500°C, but oxidation reactions are prone to occur in high temperature environments, affecting performance, so protective measures need to be paid attention to when using it. Q235 round pipes are prone to corrosion in atmospheric environments of high temperature, high humidity, and high salt. Therefore, special attention must be paid to anti-corrosion measures when used in marine environments, coastal areas, or other high-salt, high-humidity environments.
