Automotive Applications – Stainless Steel Tube & Pipe
Main Automotive Applications
- Exhaust systems: Manifolds, front/mid/tail pipes, mufflers, flex pipes
- Fuel systems: High-pressure fuel lines; feed/return lines
- Brake & hydraulic: Brake lines; ABS/ESP circuits
- EGR, turbo, emissions: EGR pipes/coolers; turbo oil lines
- Cooling & EV battery: Coolant, HVAC, battery thermal circuits
- Chassis/structural: Frames, brackets, roll structures, trims
1. Exhaust Systems – Welded Stainless Steel Tube & Pipe
We supply welded stainless tube and pipe for manifolds, front/mid/tail pipes, muffler shells, perforated cores, and flex sections. For OEM exhaust lines, ferritic grades such as 409, 439, and 441 provide a cost-effective balance of high-temperature oxidation resistance and durability. For higher corrosion resistance and premium or performance applications, austenitic grades such as 304 and 316L are commonly used.
2. EGR, Turbo & Emission Control – High-Temperature Stainless Tubes
Modern emission control systems expose materials to hot exhaust gas, condensate, and frequent thermal cycles. For these components, buyers often select austenitic grades such as 304L, 316L, 321, or 347, depending on required temperature resistance and corrosion performance.

3. Chassis & Structural Components – Mechanical Stainless Tubing
Stainless steel tubes and pipes are also used in selected structural and mechanical applications, especially where corrosion resistance, strength, or appearance are important. For these applications, buyers often choose welded mechanical tubing in grades 304 / 304L or economical ferritic grades such as 409 / 430 / 439, depending on required strength, appearance, and corrosion resistance.
