409 Stainless Steel Billets for Exhaust Systems
Primary billets of 409 ferritic stainless steel, an alloy with about 11% chromium and low carbon content, designed for high-temperature resistance in automotive exhaust systems. These are cast forms used as feedstock for subsequent forging or rolling into exhaust components. They are classified under tariff item 7218.10.00 as 'other primary forms' of stainless steel, before any hot-working.
