JFE430XT
High-formability ferritic stainless steel
<Composition> 16Cr - Ti - ultra-low C(SUS430LX)
comparison of corrosion resistance
Deep drawability
- Enhanced SUS430 stainless steel with improved drawability, ridging and weldability.
- SUS430LX series ferritic stainless steel offers markedly superior formability and ridging resistance to SUS430.
- Corrosion resistance is as good or better than that of SUS430, with excellent weld corrosion resistance and workability.
- JFE Steel offers cold tandem products (functional stainless steels) to suit your application needs.
Applications
Durable goods for daily use, kitchen equipment, decorative items, architectural interiors
