Overview
The corrosion resistance and high temperature resistance of 409 stainless steel are relatively high, and can be used in the exhaust system to increase the life of 409 stainless steel and save energy. And because of its high temperature resistance, it can achieve a high-efficiency exhaust system, reduce the thickness of the exhaust system, save energy, reduce exhaust emissions, and the cost of 409 stainless steel is low, the yield is high, and easy to replace. It is generally used in automobile exhaust emission devices to ensure the exhaust emission of automobiles and the good use of automobile tail parts. The 409 is also commonly used in many other industries. For example, domestic heating furnaces, farm installations, fuel filters, etc. These need to withstand high temperatures.
Application
Automotive exhaust systems
Catalytic converters
Mufflers
Tailpipes
Farm equipment
Structural support and hangers
Transformer cases
Furnace components
Heat exchanger tubing

Corrosion Resistance
Grade 409 stainless steels have excellent resistance to exhaust gas and atmospheric corrosion, superior to that of 410 martensitic grades with 12% chromium and 3CR12. However, the corrosion resistance is lower than that of grade 430 steels containing 17% chromium. The surface of grade 409 steels is liable to mild corrosion, which limits the usage of steels for decorative purposes.
Heat Resistance
Grade 409 stainless steels offer scaling resistance at temperatures up to 675°C during continuous operation, and up to 815°C under intermittent conditions. These temperatures pertain to specific service environments.
Heat Treatment
Annealing of grade 409 steels is carried out at temperatures ranging from 790 to 900°C, followed by air-cooling. Thermal treatment does not harden grade 409 steels.
Package Process
1.with plastic cap to protect both ends
2.weaving bag wrapped outside the pipe
3.then pack into wooden case.
