Product Description
ERW Welded Stainless Tube for Exhaust Systems
JIS G4312 Suh409L/1.4512/441/436L/439
Product Overview
Stainless steel grade 409L is a general chromium, titanium stabilized, ferritic stainless steel specifically designed for automotive exhaust systems. With 11% chromium content - the minimum required for forming the passive surface film that provides corrosion resistance - this alloy combines excellent elevated temperature corrosion resistance with medium strength, good formability, and cost-effectiveness.
Key Features
  • Superior corrosion resistance compared to carbon steel
  • Excellent high-temperature oxidation resistance
  • Good mechanical properties and formability
  • Cost-effective alternative for challenging environments
  • Ideal for applications where mechanical properties and corrosion resistance take priority over appearance
Chemical Composition
Element C Mn Si P S Cr Ni Ti
