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.

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.

Alloy TP 409 Pipes 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.

Type 409 stainless steel has a unique chemical composition that includes:

• C 10.5-11.75%
• Fe 0.08%
• Ni 0.5%
• Mn 1%
• Si 1%
• P 0.045%
• S 0.03%
• Ti 0.75% max

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.

Applications

The typical applications of grade 409 stainless steels are listed below:

• Automotive exhaust tubing
• Catalytic converter systems
• Mufflers

Heat Resistance

Grade 409 stainless steels offer scaling resistance at temperatures up to 675°C during continuous operation, and up to 815°C under intermittent conditions. These temperatures pertain to specific service environments.

Heat Treatment

Annealing of grade 409 steels is carried out at temperatures ranging from 790 to 900°C, followed by air-cooling. Thermal treatment does not harden grade 409 steels.

Welding

Grade 409 steels must be pre-heated to temperatures of 150 to 260°C before welding. Although grade 430 and 409 filler rods or electrodes can be used during welding of grade 409 steels, grade 309 electrodes or filler rods are strongly recommended by AS 1554.6. Care should be taken to weld grade 409 steels with minimum heat, in order to mitigate grain growth.

Ductility of the welded products can be improved by annealing post-welding at temperatures of 760 to 815°C. However, this is not required for thin welded products. Welding of exhaust tubing of automobiles is carried out without filler rods.
