Company Profile

Grade 409 is a stabilized ferritic general-purpose stainless steel tube featuring 11% chromium. This exceptional composition makes it ideal for applications demanding superior oxidation or corrosion resistance where carbon steel and certain coated steels fall short. With robust oxidation resistance and excellent formability, the 409 tube stands out, despite its lower chromium concentration limiting its corrosion resistance compared to grades like 304, 430, or 439. Nevertheless, it surpasses mild steel in performance. The 409 tube accommodates various forming techniques including roll forming, stretch bending, deep drawing, and press forming. Post-annealing, 409 does not harden during cold treatment processes like press or stretch bending. Its weldability is fair, though caution is advised for applications involving shock loading due to grain growth in the heat-affected zone, impacting mechanical integrity. Predominantly used in automotive exhaust systems, the 409 tube's mechanical properties provide significant benefits to the automotive and agricultural sectors, offering remarkable resistance to exhaust gases and high-temperature environments. Mechanical properties take precedence over aesthetics, making it unsuitable for decorative purposes.

GENERAL PROPERTIES:

• Alloy 409, a ferritic stainless steel enriched with chromium and titanium, serves primarily in automobile exhaust systems. Containing 11% chromium, it meets the minimum requirement for forming a passive surface layer that imparts corrosion resistance. This alloy offers exceptional corrosion resistance at high temperatures, medium strength, good formability, and cost-effectiveness. Alloy 409 outperforms carbon steel in corrosion resistance and is a preferred choice in moderately demanding conditions where both high-temperature oxidation and corrosion resistance are beneficial. It is frequently utilized in applications where mechanical properties and corrosion resistance take precedence over appearance.

APPLICATIONS:

• Initially designed for the automobile exhaust industry, Alloy 409 has proven effective in various industrial applications, including:

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:

• Exceptional resistance to atmospheric and exhaust gas corrosion
• Forms a light surface rust in most atmospheres, which impedes further corrosion but may affect appearance

HEAT RESISTANCE:

• 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

• Easily weldable
• Pre-heat of 302 to 500^oF (150 to 260^oC) is recommended
• Post-weld annealing at 1400 to 1499^oF improves weld ductility
• Post-weld annealing is unnecessary for thin sections
• Automotive exhaust tubing is typically welded without filler metal
