As a professional manufacturer and supplier based in Liaocheng, Shandong, China, Hemaokang Steel (Shandong) Co., Ltd. is proud to offer our premium 430 Stainless Steel Coil with BA Finish in strict compliance with JIS G4305 standard. Our 430 BA finished coils combine excellent corrosion resistance, high formability, and a bright, reflective surface that meets the demands of diverse industrial and decorative applications. With an annual export value exceeding US$50 million and ISO9001 certification, we ensure consistent quality and reliable supply to global markets.
The 430 grade is a ferritic stainless steel known for its good resistance to oxidation and mild corrosion, making it a cost-effective alternative to 304 in many indoor environments. The BA (Bright Annealed) finish provides a mirror-like surface that is both aesthetic and easy to clean, ideal for visible components in kitchenware, automotive trim, and home appliances. Our coils are available in thicknesses from 0.3mm to 1.5mm and a fixed width of 1250mm, with customizable coil weights to suit your production needs.

Key Features & Benefits
- Excellent Corrosion Resistance: The 430 grade offers good resistance to atmospheric corrosion, moisture, and mild acids, making it suitable for indoor applications such as kitchen sinks, cabinets, and decorative panels.
- Bright Annealed (BA) Surface: The BA finish provides a smooth, mirror-like surface that enhances aesthetic appeal and simplifies cleaning. It is ideal for visible parts where appearance matters.
- High Formability: 430 BA stainless steel can be easily bent, stamped, and deep drawn without cracking, thanks to its balanced ferritic structure. This allows manufacturers to create complex shapes with minimal waste.
- Cost-Effective Alternative: Compared to austenitic grades like 304, 430 has lower nickel content, offering a more economical solution for applications that do not require extreme corrosion resistance.
- Magnetic Properties: 430 is ferritic and magnetic, which can be an advantage in certain applications such as magnetic holders, induction cooktop components, or automotive sensors.
- Consistent Quality: Our coils are produced under strict process control, ensuring uniform thickness, flatness, and surface finish across the entire length. Each coil is tested for mechanical properties and surface defects before shipment.
- Customizable Dimensions: While standard thickness is 0.3-1.5mm and width 1250mm, we can also supply slitted coils or cut-to-length sheets upon request. Minimum order quantity is 5 tons per size.
Typical Applications
- Kitchenware & Tableware (sinks, pots, pans, trays)
- Home Appliance Panels (refrigerators, washing machines, microwave ovens)
- Automotive Trim & Exhaust Components
- Architectural Decorative Cladding & Elevator Panels
- Industrial Equipment & Chemical Containers (mild environment)
- Magnetic Components & Induction Heating Parts

Frequently Asked Questions (FAQ)
-
Q: What is the difference between BA finish and 2B finish?
A: BA (Bright Annealed) finish is produced by annealing in a controlled atmosphere furnace, resulting in a bright, mirror-like surface without further mechanical treatment. 2B finish is achieved by cold rolling followed by bright annealing and then a light skin pass, giving a slightly less reflective but still smooth surface. BA is preferred for decorative applications requiring high gloss. -
Q: Can the 430 BA coil be used for outdoor applications?
A: 430 stainless steel offers limited corrosion resistance compared to 304 or 316. It is suitable for indoor or mild outdoor environments where exposure to rain or salt is minimal. For harsh outdoor conditions, we recommend considering 304 or 316 grades. -
Q: What is the typical lead time for your coils?
A: Standard lead time is 15-20 working days after receiving deposit. For urgent orders, we can expedite production subject to stock availability. Please contact our sales team for current stock status. -
Q: Do you offer slitting or cut-to-length services?
A: Yes, we can slit the coil into narrower widths or cut it into sheets as per your specifications. Additional charges and lead time may apply. Please inquire about your requirements. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 5 tons per size and finish. For trial orders or smaller quantities, please discuss with our sales team; we may accommodate sample orders. -
Q: How do you ensure the quality of the coils?
A: We have a rigorous quality control process in place, including chemical composition analysis, mechanical property testing, surface inspection, and dimensional measurement. Each coil comes with a mill test certificate in accordance with ISO9001 standards. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% balance before shipment) and L/C at sight. Other payment methods may be negotiated on a case-by-case basis. -
Q: Can you provide free samples?
A: Yes, we can provide small samples (e.g., 200mm x 200mm) for evaluation. The sample is free, but the customer is responsible for shipping costs. Larger samples may be charged at a nominal fee.
