AK Steel 409 Ferritic Stainless steel
Categories: Metal; Ferrous Metal; Ferritic; Stainless Steel; T 400 Series Stainless Steel
Material Notes: AK Steel 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. Current applications include automotive and truck exhaust systems, including tubular manifolds; agricultural spreaders, gas turbine exhaust silencers, and heat exchangers. AK Steel 409 is also useful for "difficult-to-form" hardware such as fuel filters.
