409 409L Ferritic Stainless Steel Sheet 0.4mm-6mm Automotive Exhaust Grade Economical Alloy Plate
409 / 409L Ferritic Stainless Steel Sheet for Automotive Exhaust Applications

409 and 409L are titanium-stabilized ferritic stainless steels containing approximately 11% chromium, engineered as the cost-effective solution for automotive exhaust systems. The controlled titanium addition forms stable carbides, preventing chromium depletion at grain boundaries and improving weldability. As the most widely used stainless steel in automotive manufacturing, 409/409L offers an optimal balance of oxidation resistance, formability, and economy unmatched by any other alloy at this price point.

Key Features
  • Cost-Effective Corrosion Resistance: 11% Cr content provides adequate oxidation resistance for exhaust system service up to 675°C
  • Titanium Stabilized (409L): Low carbon + Ti addition prevents sensitization and ensures good weld ductility
  • Excellent Formability: Ferritic structure allows deep drawing and stretch forming for complex exhaust component shapes
  • Thermal Fatigue Resistance: Low thermal expansion and high thermal conductivity vs. austenitic grades
  • Stress Corrosion Cracking Immunity: Ferritic structure is virtually immune to chloride SCC, unlike 304/316
  • Magnetic Properties: Ferritic structure provides magnetic properties useful for induction cookware components
