Grade 409 stainless steel is a Ferritic steel that offers good mechanical properties and high-temperature corrosion resistance.409 Stainless Steels are especially useful for applications where oxidation or corrosion protection beyond the capacity of carbon steel and some coated steels is needed. 409 Stainless Steels are also useful for difficult-to-form hardware such as fuel filters.

|
Easy to weld and good corrosion resistance. Heavy sections are more easily available when compared to 409.
|
304
|
High heat resistance and corrosion resistance. Grade 304 is expensive.
|
321
|
Better heat resistance when compared to 304 or 409.
|
Aluminized steel
|
Cheaper than grade 409 stainless steel, but less resistant to exhaust gases.
