What Is ASTM A240 430 Stainless Steel Plate?

ASTM A240 430 stainless steel plate is a nickel-free ferritic grade (16–18% Cr) that meets the strict requirements of ASTM A240 for chromium and chromium-nickel stainless steel plate, sheet, and strip. Produced through precision cold rolling after annealing and pickling, it offers tight thickness tolerances, superior flatness, and a clean surface ideal for stamping, bending, and fabrication.

As a straight-chromium alloy specified under ASTM A240 Type 430, it provides reliable atmospheric corrosion resistance, outstanding thermal conductivity (approximately 26 W/m·K), low thermal expansion, and full magnetic properties — making it an economical and practical choice for a wide range of applications.

Available Specifications and Finishes

Gangsteel offers ASTM A240 430 stainless steel plate 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, BA, NO.4, and HL. All plates are protected with PVC or PE film to prevent scratching during transit.

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.

Manufacturing Process at Gangsteel

Our production begins with high-purity AOD-refined material to achieve exact chemistry that meets ASTM A240 requirements. Hot rolling is followed by cold rolling on precision mills for superior thickness uniformity. Annealing and pickling remove scale, followed by final inspection using eddy-current and AI visual systems. Every batch undergoes rigorous third-party testing (SGS, TUV, BV) for full traceability and ASTM compliance.

Key Advantages of Gangsteel ASTM A240 430 Plate

  • Direct compliance with ASTM A240 Type 430
  • Cost efficiency — nickel-free composition keeps pricing stable
  • Excellent formability — high ductility for complex fabrication
  • Superior thermal properties — higher conductivity and lower expansion than austenitics
  • Magnetic — easy handling in automated lines
  • Full export-ready documentation and traceability

Wide Range of Applications

ASTM A240 430 stainless steel plate is widely used in:

  • Household appliances (refrigerator liners, washing machine panels)
  • Food processing equipment (countertops, sinks)
  • Architectural cladding and elevator interiors
  • Automotive interior trim
  • Industrial heat exchangers and guards
