What Is SS 430 BA Stainless Steel Coil?

SS 430 BA stainless steel coil is a nickel-free ferritic grade that stands out for its brilliant, mirror-like surface achieved through bright annealing in a protective hydrogen-nitrogen atmosphere after cold rolling. This process leaves the coil completely scale-free and highly reflective, with gloss levels reaching 70–90% and Ra values typically under 0.1 μm. The result is a premium, mirror-bright finish that requires no extra polishing, offering both stunning aesthetics and maximum cleanliness in one step.

As a straight-chromium alloy (16–18% Cr), SS 430 BA coil gives you outstanding value — stable pricing, full recyclability, and performance that rivals more expensive austenitic grades in many non-aggressive environments. Its high thermal conductivity and low thermal expansion make it especially popular for heat-related and decorative applications.

Chemical Composition

Our SS 430 BA coils strictly conform to the chemical limits of all listed standards:

This precise chemistry ensures a stable chromium-oxide passive layer and excellent oxidation resistance up to 815 °C.

Mechanical Properties

Typical mechanical properties in the annealed condition (standard for BA finish coils):

These values deliver excellent formability for deep drawing, bending, and stamping while maintaining sufficient strength for structural and decorative uses.

Available Specifications and Finishes

Gangsteel offers SS 430 BA stainless steel coil in the following standard range (custom sizes available upon request):

• Thickness: 0.25 mm – 3.0 mm (up to 6 mm on request)
• Width: 600 mm – 2000 mm (slit or mill edge)
• Coil ID: 508 mm or 610 mm
• Coil weight: 5–25 tons

The BA finish provides the highest reflectivity and cleanliness. All coils are protected with PVC/PE film and paper interleaving to prevent scratching during transit.

Manufacturing Process at Gangsteel

Our production begins with high-purity AOD-refined material to achieve exact chemistry. Hot rolling is followed by cold rolling on 20-high Sendzimir or 4-high mills for superior thickness uniformity (±0.03 mm). Bright annealing in a controlled hydrogen-nitrogen atmosphere creates the signature mirror-like BA surface without any oxidation. Final skin-passing and inspection using eddy-current and AI visual systems guarantee defect-free material. Every batch undergoes third-party testing (SGS, TUV, BV) for full traceability.

Customers looking for the same high-quality material in other finishes or forms can also choose our a240 Type_430 stainless steel sheet, EN10088 2 X6Cr17 stainless steel sheet, DIN 1.4016 stainless steel sheet, GB/T 10Cr17 1Cr17 stainless steel sheet, or JIS G4305 SUS 430 stainless steel sheet.
