ASTM A268 TP409 / UNS S40900 / 1.4512 / SUS 409 Stainless Steel Seamless Tube
ASTM A268 TP409 / UNS S40900 / 1.4512 / SUS 409 Ferritic Stainless Steel Seamless Tube
Grade 409 is a titanium-stabilised ferritic stainless steel. Although regarded as a general-purpose chromium stainless steel the almost exclusive application for Grade 409 is automotive exhaust systems. Its applications are those where appearance is a secondary consideration to mechanical properties and corrosion resistance, particularly at high temperatures, and where some weldability is required.
