PRODUCT DETAILS

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.
409 steels are also available in highly stabilized forms, such as grades S40930, S40920 and S40910. The stability of these grades is provided by the presence of niobium, titanium, or both, in the composition of steels.

Possible Alternative Grades

Grade	Properties
3CR12	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.
