Grade 409 is a stabilized ferritic stainless steel tube containing 11% chromium, designed for general-purpose applications. This exceptional material is tailored to meet demands where oxidation or corrosion resistance is paramount, qualities that carbon steel and certain coated steels often lack. The 409 stainless steel tube stands out with its robust oxidation resistance and formability, despite lower corrosion resistance compared to grades 304, 430, or 439. However, it significantly outperforms mild steel. Techniques such as roll forming, stretch bending, deep drawing, and press forming are all viable for shaping 409. Post-annealing ensures it does not harden during cold treatment by methods like warm and roll forming, including press or stretch bending. While it boasts fair weldability, it is not recommended for structures prone to shock loading due to grain growth in the heat-affected zone, which affects mechanical integrity. Predominantly used in automotive exhaust systems, the 409 stainless steel tube's mechanical properties make it invaluable in the automotive and agricultural sectors, effectively resisting exhaust gas corrosion and high temperatures. While its mechanical attributes are paramount, it is not suited for decorative purposes due to its appearance.

GENERAL PROPERTIES:
- Alloy 409 is a ferritic stainless steel expertly stabilized with chromium and titanium, primarily designed for automobile exhaust systems. Comprising 11% chromium, it achieves the minimal threshold necessary for forming the passive surface coating that imparts corrosion resistance in stainless steels. This alloy boasts excellent corrosion resistance at elevated temperatures, medium strength, good formability, and a competitive total cost. Alloy 409 outperforms carbon steel in corrosion resistance, making it a superior choice for slightly demanding conditions where both high resistance to corrosion and high-temperature oxidation are advantageous. While it excels in mechanical properties and corrosion resistance, aesthetic considerations are secondary in its applications.
APPLICATIONS:
- Originally engineered for the automobile exhaust industry, Alloy 409 has proven its versatility across various industrial applications. Notable uses include:
- Automotive exhaust systems
- Catalytic converters
- Mufflers
- Tailpipes
- Farm equipment
- Structural support and hangers
- Transformer cases
- Furnace components
- Heat exchanger tubing
STANDARDS:
- ASTM/ASME: UNS S40900
- EU standard: FeMi35Cr20Cu4Mo2
- DIN: 2.4660
CORROSION RESISTANCE:
- Effectively resists atmospheric and exhaust gas corrosion
- In most environments, a light surface rust will develop which prevents further corrosion but detracts from the surface appearance
HEAT RESISTANCE:
- Classified as resistant to scaling in intermittent service up to 1499°F (815°C) and up to 1247°F (675°C) in continuous service
WELDABILITY
- Easily weldable
- Pre-heat recommended at 302 to 500°F (150 to 260°C)
- Post-weld annealing at 1400 to 1499°F enhances weld ductility
- Post-weld annealing is unnecessary for thin sections
- Typically, automotive exhaust tubing is welded without filler metal
