Core Strengths of 409 Stainless Steel Pipe

• Nickel-free ferritic grade, stable low cost without nickel price fluctuation risk 

• Continuous anti-oxidation performance up to 675°C for cyclic exhaust heating 

• Titanium stabilization avoids intergranular corrosion after welding, no extra heat treatment needed 

• Superior ductility, easy bending & forming for mufflers, tailpipes and exhaust headers 

• Reliable resistance to exhaust gas corrosion under long-term high temperature 

• Pass hydrostatic & NDT inspection, full MTC certification for customs clearance 

• Mass standard size stock, support mixed full container wholesale orders 

Main Applications of 409 Stainless Steel Pipe

• Automotive industry: Exhaust manifold, muffler blank, catalytic converter raw tubing 

• Construction machinery: Engine cooling pipe, low-pressure high-temperature fluid pipeline 

• Agricultural machinery: Vehicle exhaust & waste heat recovery piping 

• Medium-temperature heat exchange equipment: EGR cooler tubes for vehicle systems
