409L（14512）
TISCO
Performance of 409L (14512) Stainless Steel Pipe
Corrosion Resistance: 409L stainless steel pipe has good corrosion resistance, which is mainly due to its high chromium content (usually 10.5% - 11.5%). Chromium forms a dense oxide film on the surface of the material, effectively preventing oxidation and corrosion. Even in humid or salty environments, 409L stainless steel can still show good corrosion resistance.
High-Temperature Performance: 409L stainless steel can still maintain good mechanical properties at high temperatures, especially in oxidizing environments, its oxidation resistance is particularly outstanding. Its temperature limit is (-20℃ to 650℃), and the thermal fatigue life (650℃ cycle) can reach 3000 cycles.
Mechanical Properties: The yield strength of 409L stainless steel is 280MPa, the tensile strength is 480MPa, the elongation is 25%, and the hardness is 180HB.
Processability: 409L stainless steel has good processability, including stamping, drawing, welding, etc. Its welding efficiency is high, and the forming energy consumption is low.
Cost Advantage: The cost of 409L stainless steel is relatively low, mainly due to its low nickel content. Compared with high-end stainless steel such as 304 and 316, the price of 409L stainless steel is more affordable.
Main Applications of 409L Stainless Steel Pipe in the Automotive Industry
Exhaust System:
Exhaust Manifold: The exhaust manifold is directly installed on the engine, and the exhaust gas temperature can reach around 900℃. The material is required to have excellent oxidation resistance, high-temperature strength, and thermal fatigue performance. 409L stainless steel pipe can meet these requirements, and its thermal fatigue characteristics are superior to austenitic stainless steel because of its small thermal contraction coefficient.
Catalytic Converter Shell: The catalytic converter is used to purify exhaust gases and needs to withstand high temperatures and vibrations and other harsh environments. 409L stainless steel pipe has good high-temperature strength, high-temperature salt corrosion resistance, and processability, making it suitable for the shell of the catalytic converter.
Muffler: The corrosion resistance of 409L stainless steel pipe makes it an ideal material for making mufflers, which can work under extreme conditions and provide excellent sound attenuation effects.
Tailpipe: The tailpipe is exposed at the rear of the vehicle. In addition to corrosion resistance, it is also required to have an attractive appearance. 409L stainless steel pipe can meet these requirements.
Other Components:
Engine Oil Pipes, Water Pipes, EGR Pipes: 409L stainless steel pipe has good mechanical processing properties such as bending and heading, no hardening phenomenon after heat treatment, high pressure resistance, and corrosion resistance, making it suitable for these components.
