430 Stainless Steel Bright Annealed Sheet
Leave a message
Are you looking for a cost-effective, corrosion-resistant, and bright-finished stainless steel sheet for industrial or decorative applications? 430 bright annealed stainless steel sheet is a ferritic stainless steel widely used in applications requiring moderate corrosion resistance, magnetism, and excellent surface finish, suitable for home appliances, automotive parts, kitchen equipment, and building materials.
What Is 430 Stainless Steel Bright Annealed Sheet?
430 stainless steel is a ferritic, chromium-rich stainless steel (≈17% Cr, ≤0.12% C), offering good corrosion resistance and formability. The bright annealed (BA) finish is produced by annealing in a controlled atmosphere furnace and then rapidly cooled to achieve a smooth, reflective, uniform surface, ideal for decorative and hygienic applications.

What is the difference between 430 BA and 430 No.1/2B finish?
The difference between 430 BA and 430 No.1/2B finish is that BA (Bright Annealed) is polished in a controlled annealing atmosphere to produce a smooth, reflective surface with Ra ≤0.1 µm, while No.1/2B is a matte or dull finish with uniform silver-gray appearance.
Can 430 stainless steel bright annealed sheet be used in kitchens?
430 stainless steel bright annealed sheets are commonly used in kitchens for appliances, backsplashes, and counters because they resist oxidation and staining, although their corrosion resistance is lower than 304 stainless steel in highly humid or acidic conditions.
What thicknesses and widths are available for 430 BA sheets?
430 BA sheets are typically available in thicknesses from 0.3 mm to 6 mm and standard widths up to 1,250 mm, with custom sizes available upon request.
Is 430 BA stainless steel magnetic?
Yes, 430 BA stainless steel is magnetic due to its ferritic structure, which allows it to be used in applications requiring magnetic properties.
How does 430 BA compare with 304 for decorative applications?
Compared with 304, 430 BA is less corrosion-resistant but offers similar aesthetic qualities for decorative applications, making it suitable for indoor or low-moisture environments where cost-effectiveness is important.
Packaging and Shipping
Packaging: Each sheet or coil is wrapped in moisture-proof paper, lined with plastic film, and secured with steel straps. The outer layer is protected by wooden pallets or crates to ensure safety during international transportation.
Labeling: Each package includes the furnace number, grade, dimensions, and standard information.
Delivery Time: Usually within 7-15 business days after receiving the advance payment.
Shipping Method: Sea freight (full container/less than container load), air freight, or express delivery, depending on customer requirements.
