409 Stainless Steel Sheet

409 is a 12% chromium, titanium stabilised ferritic stainless steel. It has fair resistance to corrosion and oxidation at high temperatures. In the annealed condition 409 is ductile, does not work harden and can be formed using a variety of roll forming, bending or mild pressing/ stamping operations. 409 is resistant to stress corrosion cracking but has limited weldablity.

409 should not be used in the as-welded condition for dynamic or impact loaded structures.

Use: Ferritic stainless steel stabilised using titanium. It was designed for use in automotive exhaust systems where higher temperature corrosion resistance than mild steel/galvanised is required. It may develop a light patina in use but withstands general environmental corrosion well. It is also used in electrical kiosks and distribution boxes.
