Ferritic 409 Stainless Steel Possible Alternative Grade

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.
