430 Stainless Steel Plate
430 stainless steel plate is a ferritic, straight chromium stainless steel offering excellent corrosion resistance, good formability, and cost-effective performance across a wide range of industrial and commercial applications. As a trusted supplier with mill-direct pricing and ready stock, we provide high-quality 430 SS plates that meet international standards for demanding environments.
What Is 430 Stainless Steel Plate?
Grade 430 is a non-hardenable ferritic stainless steel containing approximately 16–18% chromium and a low carbon content. Unlike austenitic grades such as 304 or 316, the 430 stainless steel plate does not contain nickel, which significantly reduces material costs while still delivering reliable performance in mildly corrosive environments. It offers moderate resistance to oxidation at elevated temperatures, making it a popular choice across multiple industries.
Key Specifications of 430 SS Plate
Our 430 stainless steel plates are available in a broad range of dimensions and finishes to meet specific project requirements:
- Standard: ASTM A240, EN 10088-2, JIS G4304
- Thickness: 0.5 mm – 100 mm
- Width: Up to 2,500 mm
- Length: Up to 12,000 mm (custom cutting available)
- Surface Finish: 2B, BA, No.4, No.1, Mirror (8K)
- Hardness: ≤ 183 HB (annealed condition)
- Tensile Strength: ≥ 450 MPa
- Yield Strength: ≥ 205 MPa
Chemical Composition
The chemical makeup of 430 grade stainless steel plate is carefully controlled to ensure consistent mechanical properties and corrosion resistance:
- Chromium (Cr): 16.0% – 18.0%
- Carbon (C): ≤ 0.12%
- Manganese (Mn): ≤ 1.00%
- Silicon (Si): ≤ 1.00%
- Phosphorus (P): ≤ 0.040%
- Sulfur (S): ≤ 0.030%
- Nickel (Ni): ≤ 0.75%
Performance Advantages of 430 Stainless Steel Plate
Choosing 430 stainless steel plate delivers several notable benefits for engineers and procurement professionals:
- Cost Efficiency: Nickel-free composition reduces raw material costs compared to 304 or 316 grades, offering excellent value without compromising quality.
- Corrosion Resistance: Performs well in mild atmospheric and chemical environments, resisting oxidation and staining effectively.
- Heat Resistance: Maintains structural integrity at continuous service temperatures up to 870°C, suitable for high-temperature applications.
- Magnetic Properties: Ferritic structure makes it magnetic, which is advantageous in certain manufacturing and processing operations.
- Good Formability: Easily fabricated through bending, stamping, and deep drawing processes, accommodating complex component designs.
- Aesthetic Appeal: Available in polished and brushed finishes for decorative and architectural applications.
Industry Applications
The versatility of 430 stainless steel plate makes it a preferred material across diverse sectors:
- Kitchen Equipment: Countertops, sinks, cookware, and commercial kitchen appliances benefit from its hygienic surface and corrosion resistance.
- Automotive Industry: Used in trim, exhaust systems, and decorative components due to its heat resistance and attractive finish.
- Architecture & Construction: Cladding panels, elevator interiors, handrails, and façade elements leverage its aesthetic and durable properties.
- Appliance Manufacturing: Refrigerator panels, washing machine drums, and dishwasher liners commonly use 430 grade plate.
- Chemical Processing: Suitable for mild chemical environments where moderate corrosion resistance is required at a lower cost.
- Food Processing: Compliant with food-grade standards for equipment used in food preparation and packaging lines.
