Automotive Stainless Steel Tube 19.05x1.2x20ft S409000 Ferrtic Tube
ASTM A268 409 409L 1.4512 stainless steel is an alloy designed principally for the automotive exhaust industry, although it has been used successfully in other industrial applications. It combines good elevated temperaturecorrosion resisitance with medium strength, good formability and overall cost. 409L stainless steel is highly resistant to high temperatures, achievable engine and exhaust systems, and reduces the thickness of the exhaust system to reduce exhaust emissions. Low cost, good flexibility, high yield, easy replacement, and environmentally friendly new products.
409 is a titanium stabilised ferritic stainless steel. Although regarded as a general-purpose chromium stainless steel the primary application for Grade 409 is automotive exhaust systems. Its applications are those where appearance is a secondary consideration to mechanical properties and corrosion resistance and where some weldability is required.
Type 409 is a ferritic stainless steel that has a good combination of heat resistance and corrosion resistance. Its titanium stabilized low nickel content provides for an economical metal to corrosion resistance and oxidation resistance.
Typical Manufacturing Specifications:
- Harding by heat treatment
- High hardness with good ductility
- Good corrosion resistance capability
- Good wear corrosion resistance
- High cold-deformation property

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.
