What Is Grade 430 Cold Rolled Stainless Steel Coil?

Grade 430 cold rolled stainless steel coil is a versatile nickel-free ferritic grade (16–18% Cr) engineered for excellent formability, thermal performance, and cost efficiency. Through precision cold rolling after hot rolling and annealing, the coil achieves tight thickness tolerances, superior flatness, and a clean surface ready for further processing into sheets, strips, or finished parts. As a straight-chromium alloy, it forms a stable passive oxide layer that protects against atmospheric corrosion while delivering outstanding thermal conductivity and low thermal expansion — properties that make it outperform austenitic grades like 304 in many heat-management situations.

The absence of nickel keeps pricing stable and makes the material fully recyclable, which is why Grade 430 cold rolled stainless steel coil remains a top choice for high-volume manufacturers in appliances, automotive, architecture, and industrial equipment.

Chemical Composition

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

This balanced chemistry ensures reliable corrosion resistance, good weldability, and oxidation resistance up to 815 °C.

Mechanical Properties

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

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

Available Specifications and Finishes

Gangsteel offers Grade 430 cold rolled 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

Common finishes include 2B (industrial matte), BA (bright annealed mirror), NO.4 (satin), and HL (hairline). All coils are protected with PVC/PE film and paper interleaving to prevent damage during transit.

Manufacturing Process at Gangsteel

Our production starts 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.

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.

Key Advantages of Gangsteel Grade 430 Coil

• Cost efficiency — nickel-free composition reduces price by 30–50% versus SUS304
• Superior thermal properties — higher conductivity and lower expansion than austenitics
• Excellent formability — high ductility for complex deep drawing
• Magnetic — easy automated handling and separation
• Consistent quality — ISO 9001 and IATF 16949 certified processes
• Full customization — any standard, finish, or size on request

Wide Range of Applications

Grade 430 cold rolled stainless steel coil is widely used in:

• Household appliances (refrigerator doors, washing machine panels, range hoods)
• Automotive trim and exhaust components
• Architectural cladding and elevator interiors
• Kitchen equipment and food processing surfaces
• Heat exchangers, radiant tubes, and industrial conveyors
• Solar panel frames and lighting reflectors
