Automotive tubing must simultaneously meet stringent requirements for performance, durability, and aesthetics. It is a high-performance component:
It offers excellent cold formability, adapting to the complex piping layout within the vehicle body;
It is highly corrosion-resistant, resisting the effects of exhaust fumes, oil, and the external environment;
and it offers an exceptionally smooth surface finish on exposed parts.
Our seamless tubing meets these comprehensive requirements, making it a reliable choice for the modern automotive industry.

TP304L is an ideal material for automotive applications:

Its excellent ductility and formability ensure crack-free processing, making it suitable for the manufacture of complex pipe bends, such as those found in exhaust systems.

Its corrosion resistance is excellent, effectively withstanding corrosion from road conditions and exhaust condensate.

As a low-carbon grade, TP304L offers excellent weldability, maintaining good corrosion resistance even after welding during component manufacturing, ensuring long-term component durability.

The SMLSCO polishing process gives the Seamless Tube a smooth and clean interior, improving exhaust system airflow and meeting the high cleanliness requirements of various fluid lines. This uniform, smooth surface enhances the vehicle's overall appearance, meeting the high-quality aesthetics demanded by modern automobiles. This is especially true for exposed components like exhaust tailpipes and body moldings. It combines functionality with aesthetics.

SMLSCO TP304L polished seamless tube is widely used in the automotive industry:
Durable, corrosion-resistant exhaust systems (including mufflers and exhaust pipes);
Fuel delivery lines, brake hydraulic lines, and other fluid circulation systems;
Automobile structural components, as well as interior and exterior trim.
