AI Technical Summary
Technical Problem
Ferritic stainless steel muffler hangers have high strength but poor workability, while austenitic stainless steel has excellent workability but risks stress corrosion cracking, necessitating a solution that balances corrosion resistance and workability.
Method used
A muffler hanger composed of an iron-based core material with an aluminum-based outer shell, and an intermediary member with layers of aluminum and iron for welding, ensuring high corrosion resistance without compromising workability.
Benefits of technology
The solution provides a muffler hanger with enhanced corrosion resistance while maintaining processability, and a secure connection between the muffler hanger and muffler that prevents leakage of exhaust gases.
