comparison of corrosion resistance
Weldability
Corrosion resistance
- This ferritic stainless steel (ultra-low C, N, and added Ti), manufactured using advanced smelting technology, is compatible with excellent formability and corrosion resistance.
- Excellent corrosion resistance against automobile exhaust gas water of condensation.
- Made using an optimized production process of tandem cold rolling and CAL annealing and pickling, resulting in exception cost performance.
Applications
- DPF, SCR, SCR (diesel)
- Exhaust heat collectors
- Mufflers, muffler cutters, exhaust gas pipes, etc.
