What Is 20 Gauge 430 Cold Rolled Stainless Steel Sheet?

20 gauge 430 cold rolled stainless steel sheet is a nickel-free ferritic grade (16–18% Cr) that delivers an excellent balance of corrosion resistance, formability, and economy. After precision cold rolling, annealing, and pickling, it achieves tight thickness control and a clean, uniform surface ready for stamping, bending, or fabrication. The 0.912 mm thickness strikes the perfect balance — thin enough for easy forming and low weight, yet thick enough for good rigidity.

As a straight-chromium alloy, it offers stable pricing, high thermal conductivity (approximately 26 W/m·K), low thermal expansion, and full magnetic properties, making it a favorite for appliances, automotive trim, and architectural applications.

Chemical Composition

Our 20 gauge 430 sheets strictly conform to the chemical limits of all listed standards:

Chromium (Cr)

16.00–18.00

Manganese (Mn)

≤1.00

Silicon (Si)

≤1.00

Phosphorus (P)

These properties make 20 gauge 430 sheet highly formable for deep drawing and bending while providing sufficient strength for everyday use.

Available Specifications and Finishes

Gangsteel offers 20 gauge 430 cold rolled stainless steel sheet in the following standard range (custom sizes available upon request):

  • Thickness: 0.912 mm (20 gauge) ±0.04 mm
  • Width: 600 mm – 2000 mm (slit or mill edge)
  • Length: Up to 6000 mm
  • Tolerance: Flatness ≤8 mm/m

Common finishes: 2B, BA, NO.4, HL. All sheets are protected with PVC/PE film for safe handling.

For customers who also need coil form or other gauges, we recommend our a240 Type_430 stainless steel sheet or JIS G4305 SUS 430 stainless steel sheet.

Manufacturing Process at Gangsteel

We start with high-purity AOD-refined material, hot roll, then cold roll to exact 20 gauge thickness on precision mills. Annealing and pickling ensure a clean base, followed by final inspection using eddy-current and AI visual systems. Every batch undergoes third-party testing (SGS, TUV, BV) for full traceability.

For European or Chinese standard projects, the identical material is also available as our EN10088 2 X6Cr17 stainless steel sheet, DIN 1.4016 stainless steel sheet, or GB/T 10Cr17 1Cr17 stainless steel sheet.
