Company Profile

Grade 409 is a stabilized ferritic stainless steel tube, enriched with 11% chromium, designed for general-purpose applications where superior oxidation and corrosion resistance are essential. Unlike carbon steel and certain coated steels, our 409 tube offers robust oxidation resistance and exceptional formability. Despite having lower corrosion resistance compared to grades 304, 430, or 439, 409 outshines mild steel in performance. It can be effectively shaped using roll forming, stretch bending, deep drawing, and press forming techniques. Post-annealing, 409 does not harden when subjected to cold treatments like warm and roll forming processes, such as press or stretch bending. It also boasts decent weldability; however, it is not advisable for use in shock-loaded structures due to grain growth in the heat-affected zone, impacting mechanical quality. Primarily utilized in automotive exhaust system applications, the 409 tube's mechanical properties provide a significant edge in the automotive and agricultural sectors. It withstands corrosion from exhaust gases and high-temperature environments effectively. However, its mechanical prowess outweighs its aesthetic attributes, making it unsuitable for decorative purposes.

Leading Stainless Steel Sheet Suppliers in China

GENERAL PROPERTIES:

• Alloy 409 is a ferritic stainless steel that has been stabilised with chromium and titanium. Its principal application is automobile exhaust systems. It includes 11% chromium, which is the minimal amount required for the creation of the passive surface coating that provides stainless steels with corrosion resistance. It has strong corrosion resistance at elevated temperatures, medium strength, decent formability, and an affordable total price. Alloy 409 resists corrosion more strongly than carbon steel and is used as an alternative to carbon steel in slightly demanding conditions where its high resistance to corrosion and high temperature oxidation provide an advantage. It is often employed in applications where appearance is secondary to mechanical qualities and corrosion resistance.

APPLICATIONS:

• Although Alloy 409 was originally intended for the automobile exhaust industry, it has been effectively used in a variety of other industrial applications. Some examples of applications that require Alloy 409 include:

1. Automotive exhaust systems
2. Catalytic converters
3. Mufflers
4. Tailpipes
5. Farm equipment
6. Structural support and hangers
7. Transformer cases
8. Furnace components
9. Heat exchanger tubing

STANDARDS:

• ASTM/ASME: UNS S40900
• EU standard: FeMi35Cr20Cu4Mo2
• DIN: 2.4660

CORROSION RESISTANCE:

• Resists atmospheric and exhaust gas corrosion
• In most atmospheres a light surface rust will form which inhibits further corrosion but makes the surface less appealing

HEAT RESISTANCE:

• Generally classified as resistant to scaling in intermittent service up to 1499^oF (815^oC ) and up to 1247^oF (675^oC) in continuous service

WELDABILITY

• Readily weldable
• Pre-heat of 302 to 500^oF (150 to 260^oC) is recommended
• Post-weld annealing at 1400 to 1499^oF improved weld ductility
• Post-weld annealing is not required when welding thin sections
• Automotive exhaust tubing is typically welded without filler metal
