Stainless Steel 409

Stainless Steel - Grade 409

FERRETIC STEEL is ‘ALL INDIA METAL CORPORATION’ one of the signature material. We supply 409 in various forms to customers virtually anywhere in the world!

Grade 409 stainless steel is a Ferritic steel that offers good mechanical properties and high-temperature corrosion resistance. It is commonly considered as a chromium stainless steel, with applications in exhaust systems of automobiles and applications that demand weldability.

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.

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.

The typical applications of grade 409 stainless steels are listed below:

• Automotive exhaust tubing
• Catalytic converter systems
• Mufflers
