430 cold rolled stainless steel sheet is a high-performance ferritic grade (ASTM A240 / EN 1.4016) containing 16–18% chromium.
It is widely recognized for its excellent corrosion resistance, magnetic properties, and superior thermal conductivity compared to 304 stainless steel, all at a more competitive cost.
Huaxiao Metal supplies custom-cut 430 sheets (0.2mm–8mm) in 2B, BA, No.4, and mirror finishes, ideal for kitchen appliances, automotive trim, and elevator panels.

Surface Finish Options for 430 Stainless Steel Sheets
1. 2B Finish – Standard & Most Popular
Why Choose 2B: Excellent flatness, high consistency, and ready for further industrial processing or stamping.
Common Applications: Industrial panels, deep-drawing parts, home appliances, and kitchenware bases.
2. Optional Surface Treatments (Customizable)
Beyond the standard 2B surface, we provide the following finishes to enhance the visual appeal and functionality of your products:
BA Finish (Bright Annealed):
A mirror-like, highly reflective surface processed in a controlled atmosphere furnace. Ideal for refrigerator panels, automotive trim, and decorative kitchen covers.No.4 / Hairline Finish (Brushed):
Features continuous long or short polishing lines (Satin finish). Perfect for elevator doors, interior wall cladding, and high-end commercial kitchen equipment where anti-fingerprint properties are needed.8K Mirror Finish:
The highest level of mechanical polishing, creating a true reflection. Mostly used for luxury architectural decoration and signage.
Core Benefits of 430 Cold Rolled Stainless Steel Sheets
High Cost-Efficiency: As a nickel-free stainless steel, 430 offers much more stable pricing and a lower cost than 304 or 316 grades, making it ideal for budget-conscious large-scale projects.
Excellent Corrosion Resistance: It provides strong resistance to nitric acid, organic acids, and atmospheric corrosion, ensuring durability in indoor and mild outdoor environments.
Natural Magnetic Properties: Unlike the 300-series, 430 is naturally magnetic. This is a critical requirement for induction-compatible kitchenware and magnetic surface applications.
Superior Thermal Conductivity: 430 has better heat transfer capabilities than 304, which is why it’s widely used in heat exchangers and cooking appliances.
Versatile Surface Aesthetics: Whether you need a high-reflectivity 8K Mirror finish or a modern Brushed (Hairline) look, 430 takes polishing exceptionally well.
Technical Performance & Material Science
Grade 430 is a high-chromium ferritic stainless steel, often referred to in the industry as 18/0 stainless steel (16–18% Chromium, 0% Nickel). This unique composition makes it a high-performance yet cost-effective alternative to 304 grade for specific industrial and decorative applications.
Physical Properties (At 20°C / 70°F)
Density: 7.74 g/cm³ (0.28 lb./in³)
Thermal Conductivity: 26.1 W/m-K (Ideal for heat transfer applications)
Modulus of Elasticity: 200 GPa
Electrical Resistivity: 60 μ ohm.cm
Heat Resistance & Treatment
- Service Temperature: Reliable up to 815°C (1500°F) in continuous service and 870°C (1600°F) in intermittent use.
Annealing (Standard): 705°C – 790°C (1300°F – 1450°F).
Forging Range: 815°C – 1120°C (1500°F – 2050°F).
Comparative Advantage: 430 (18/0) vs. 304 (18/8)
Higher Thermal Conductivity: Better heat distribution than 304 stainless steel.
Magnetic Properties: Unlike 304, 430 is magnetic, which is essential for induction-compatible cookware and magnetic signage.
- Cost Efficiency: As a nickel-free grade, 430 provides a much more stable and lower price point, making it the most economical choice for large-scale indoor projects and appliance manufacturing.

FAQ
Is the surface flat enough for precision laser cutting?
Yes. Our 430 sheets undergo specialized tension leveling. We also provide “Laser-Film” (Fiber or CO2) to ensure the surface remains scratch-free during your automated cutting process.
What finishes are best for kitchen appliances?
For a modern look, we recommend BA (Bright Annealed) or No.4 (Brushed) finishes. We also offer Anti-fingerprint coating, which is highly popular among European appliance manufacturers.
Do you export to Europe and South America?
Yes — we have extensive export experience with European and South American customers.
Do you provide international certificates?
Yes. EN 10204 3.1/MTC documentation is available for all orders.
Can I get a sample of 430 stainless steel to test the surface finish and formability?
Yes, free samples are available. We provide standard size (e.g., 100x100mm) samples for you to verify the 2B/BA/No.4 finish and perform bending tests. You only need to cover the courier cost, which will be deducted from your first bulk order.
How long is the lead time for a 20ft container of 430 cold rolled sheets?
For standard specifications (0.2mm-3.0mm thickness), we maintain a permanent stock, allowing for shipment within 7-10 days. For customized dimensions or special surface treatments, the lead time is typically 15-20 days. We also offer “Green Channel” production for urgent project requirements.
