TP304L Polished Seamless Tube ASTM A269 for Automotive

Our TP304L polished seamless tubing meets the stringent requirements of automotive applications with excellent formability and high-quality finish. Manufactured to ASTM A269 standards through cold drawing process, these tubes feature a polished surface (320# OD) for superior performance.

• Excellent cold formability for complex piping layouts
• Superior corrosion resistance against exhaust fumes and environmental factors
• Smooth surface finish for exposed components
• Seamless construction for enhanced durability

TP304L stainless steel offers exceptional benefits for automotive applications:

• Excellent ductility and formability prevents cracking during complex pipe bending
• Superior corrosion resistance against road conditions and exhaust condensate
• Low-carbon composition ensures excellent weldability while maintaining corrosion resistance

Our precision polishing process delivers:

• Smooth interior surfaces for optimal fluid flow
• High cleanliness standards for fluid lines
• Enhanced aesthetic appearance for exposed components

• Exhaust systems (mufflers, exhaust pipes)
• Fuel delivery lines and brake hydraulic systems
• Structural components and exterior trim

We specialize in customized solutions for automotive OEMs:

• Multiple surface finish options including pickling, passivation, and high-precision polishing
• Custom outer diameters and wall thicknesses
• Precision cut-to-length products
• Process optimization to reduce waste and improve efficiency
