What Is SUS 430 Cold Rolled Stainless Steel Sheet?

SUS 430 cold rolled stainless steel sheet is a nickel-free ferritic grade (16–18% Cr) that offers an outstanding balance of corrosion resistance, formability, and economy. Produced through precision cold rolling after hot rolling and annealing, the sheet achieves tight thickness tolerances, superior flatness, and a clean surface ideal for stamping, bending, and fabrication. As a straight-chromium alloy, it forms a stable passive oxide layer that protects against atmospheric corrosion while providing excellent thermal conductivity and low thermal expansion — properties that outperform austenitic grades like 304 in heat-management applications.

The absence of nickel makes SUS 430 cold rolled stainless steel sheet highly price-stable and fully recyclable, making it the preferred choice for high-volume manufacturers in appliances, automotive, architecture, and industrial equipment.

Chemical Composition

Our SUS 430 sheets strictly conform to the chemical limits of all listed standards:

This precise chemistry ensures excellent weldability, oxidation resistance up to 815 °C, and long-term durability.

Mechanical Properties

Typical mechanical properties in the annealed condition (standard for cold rolled sheets):

These values deliver outstanding formability for deep drawing, bending, and stamping while maintaining sufficient strength for structural applications.

Available Specifications and Finishes

Gangsteel offers SUS 430 cold rolled stainless steel sheet in the following standard range (custom sizes available upon request):

• Thickness: 0.3 mm – 3.0 mm (up to 6 mm on request)
• Width: 600 mm – 2000 mm (slit or mill edge)
• Length: Up to 6000 mm
• Tolerance: Thickness ±0.03 mm, width ±0.5 mm, flatness ≤8 mm/m

Common finishes include 2B (industrial matte), BA (bright annealed mirror), NO.4 (satin), and HL (hairline). All sheets are protected with PVC/PE film 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). Annealing under controlled atmosphere restores ductility, followed by pickling, skin-passing, and final inspection using eddy-current and AI visual systems. Every batch undergoes third-party testing (SGS, TUV, BV) for full traceability.

For customers requiring the same high-quality material in coil form or other finishes, we recommend 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.
