Product Description
Automotive Exhaust Grade 430 Stainless Steel Coil
This automotive exhaust grade 430 stainless steel coil is a ferritic chromium alloy cold rolled strip specifically developed for the harsh thermal and corrosive environment of vehicle exhaust systems. With chromium content between 16.00-18.00% and a fully ferritic microstructure, the material delivers dependable oxidation resistance at elevated operating temperatures while maintaining excellent formability for deep drawn muffler shells, resonator bodies, and exhaust pipe blanks.
Every coil is produced from Baosteel or TISCO certified base metal and shipped with a complete Mill Test Certificate, allowing fabricators to verify chemical composition, mechanical values, and traceability before the strip enters their production line.
The 430 grade is widely recognized in the automotive supply chain as a cost-effective alternative to austenitic grades for non-structural exhaust components, offering strong scaling resistance, low thermal expansion, and good fatigue behavior under vibration.
Key Features
- Heat Resistance: Reliable oxidation and scaling resistance up to 870°C intermittent service and 815°C continuous service
- Stable Ferritic Structure: Low thermal expansion coefficient reduces distortion and thermal fatigue
- Excellent Formability: Annealed cold rolled microstructure supports deep drawing, bending and roll forming without edge cracking
- Consistent Gauge Control: Thickness tolerance of ±0.02mm ensures uniform wall thickness for welded assemblies
- Welding Friendly: Clean chemistry allows TIG, MIG and resistance seam welding with predictable bead quality
- Traceable Raw Material: Baosteel or TISCO base coils supplied with Mill Test Certificate for full material traceability
- Custom Slitting: Width from 600mm down to custom slit dimensions with burr-free edges

Applications
This coil is engineered for automotive exhaust system components including:
- Muffler outer shells
- Baffle plates
- Resonator housings
- Exhaust pipe blanks
- Heat shields
- Hanger brackets and clamp strips
Beyond passenger vehicles, it suits commercial truck silencers, agricultural machinery exhausts, generator set mufflers, marine exhaust lagging, catalytic converter housings, and diesel exhaust fluid system brackets where moderate temperature oxidation resistance and corrosion protection are required.
Packaging & Quality Assurance
Each coil is protected with anti-rust oil, wrapped in waterproof kraft paper and plastic film, secured with steel strapping, and packed on fumigated wooden pallets or export crates to withstand long ocean freight.
Full inspection documentation includes Mill Test Certificate, dimensional report, and surface quality record. The production line operates under ISO 9001:2015 and IATF 16949 quality systems, with third-party inspection (SGS) available before shipment.
Engineering support is provided for grade selection, slitting layout advice, and welding parameter guidance to maximize yield in every exhaust component program.
