comparison of corrosion resistance
Weldability
Corrosion resistance
- This ferritic stainless steel (ultra-low C, N, added Ti), manufactured using advanced smelting technology, combines excellent formability and corrosion resistance.
- Made using an optimized production process of tandem cold rolling and CAL annealing and pickling, resulting in exception cost performance.
Applications
- Stainless steel parts/materials for automobiles
- Mufflers, muffler cutters, exhaust gas pipes, etc.
