BA Finish
Mirror-like ReflectivityThe "Magnetic" Stainless Steel
What makes Grade 430 different? It's all about the Ferritic structure. It contains Chromium (16-18%) but little to no Nickel.
Ferritic Structure
Unlike austenitic 304, 430 has a Body-Centered Cubic (BCC) crystal structure. This makes it magnetic and highly resistant to stress corrosion cracking.
Corrosion Resistance
Excellent resistance to nitric acid and sulfur gases. Ideally suited for indoor appliances and dry environments. *Not recommended for coastal use.
Formability & Drawing
430 has good deep drawing properties, making it perfect for stamped parts like sinks, bowls, and trim moldings.
Don't be fooled. Magnetism doesn't mean low quality. It means it's Grade 430 Ferritic Steel. This property makes it perfect for induction cookware bottoms and magnetic boards.
Cost Index Comparison
*Eliminating Nickel significantly stabilizes the price against market fluctuations.
Surface Finishes & Specifications
Grade 430 is renowned for its aesthetic appeal. Choose the right finish for your application.
BA (Bright Annealed)
Mirror-like, highly reflective finish. Produced by annealing in a controlled atmosphere.
Best for: Home appliances (dishwashers), auto trim, reflectors.
2B (Cold Rolled)
Smooth, matte grey, slightly reflective. The standard mill finish.
Best for: Industrial applications, deep drawing parts, unseen structural components.
No.4 (Brushed)
Polished with grit lines (short parallel lines). Often coated with PVC film.
Best for: Elevator doors, kitchen equipment, architectural cladding.

Industries Powered by Grade 430
Grade 430 is the global standard for indoor applications where aesthetics and cost-efficiency matter most.
Home Appliances (White Goods)
The primary choice for dishwasher panels, range hoods, and refrigerator doors. The BA finish matches chrome fixtures perfectly at a fraction of the cost.
Kitchenware & Cookware
Essential for modern cookware. Grade 430 is used for the bottom layer of pots to ensure compatibility with induction stovetops.
Automotive Trim & Systems
Used for interior trim molding and exhaust system components. 430 resists oxidation at higher temperatures better than standard carbon steel.
Interior Architecture
Ideal for elevator doors, lobby wall cladding, and column covers. In dry indoor environments, it maintains its shine indefinitely without rusting.
Protecting Your Surface
For BA and No.4 finishes, scratches are unacceptable. We use a 3-layer protection standard to ensure goods arrive in perfect condition.
1. PVC Film Coating
Every BA/No.4 sheet is covered with 50-80 micron PVC film to prevent surface scratches during handling and fabrication.
2. Waterproof Packing
Inside the pallet, sheets are wrapped in waterproof kraft paper to prevent moisture ingress and "white rust" during sea transport.
3. Export Wooden Pallet
Strong, fumigated wooden pallets tailored to sheet size. Reinforced with steel strips to prevent shifting or deformation.
