Grade 409/409L is a titanium stabilized Ferritic Stainless Steel , most commonly known for use in automotive exhaust systems. It features good mechanical properties and high temperature corrosion resistance. As a matter of fact, 409 / 409L as a chromium Stainless Steel can also be used in applications where weldability and corrosion protection are demanded. Although it is susceptible to rust formation, rarely used for decoration purpose, 409 / 409L stainless steel demonstrates excellent corrosion resistance against gas corrosion.
is suitable for service in highly corrosive conditions and where high strength is required. The properties of this alloy are being widely used in offshore oil and gas exploration and production and in heat exchangers in petrochemical and chemical processing.
Available Tube Product Forms:
Used for parts requiring a combination of good strength and toughness, plus reasonable corrosion resistance. Typical applications are: Bolts, Bushings, Fasteners, Gas Turbine Parts, Mine Equipment, Pump Parts, Petrochemical Equipment, Steam Turbine Parts, Studs, Valve Parts etc.
Material magnetic in all conditions.
