ASME SA240M Cold Rolled 420 430 Iron Strip 0.5mm Annealed 410 Stainless Steel Strips Magnetic Corrosion-Resistant & Easy to Fabricate
Product Description
430 stainless steel strip is a ferritic stainless steel strip characterized by its high chromium content (16-18%) and negligible nickel content, making it an economical and practical stainless steel material, also known as "stainless iron" in the industry. Standard Specifications: Thickness: 0.02-3.0 mm Width: 3.5-600 mm (typically defined as steel strip when ≤600mm) Surface Finishes: NO.1, 2B, BA, No.4, 8K (mirror), HL (brushed), etc. Hardness: Customizable HV145-680 Chemical Composition (Weight Percentage)

Core Features & Advantages 1. Cost-Effective 40% lower price than 304 stainless steel, an ideal alternative for dry environment applications. Market price of cold-rolled coils: approximatelyRMB 7,550-7,600 per ton(September 2025). 2. Excellent Thermal Performance Superior thermal conductivity compared to austenitic stainless steel (304/316), suitable for heat dissipation applications. Low coefficient of thermal expansion, reducing deformation under temperature changes. Heat fatigue resistance, ideal for cyclic heating environments. 3. Superior Workability Excellent deep drawing performance, comparable to 304 stainless steel. Added stabilizer titanium ensures excellent weld mechanical properties. Suitable for cold working and bending, customizable into various shapes. Production Process Standard Production Flow: plaintext Hot Rolling → Annealing, Shot Blasting & Pickling → Cold Rolling → Annealing & Pickling → (Optional: Tempering/Surface Treatment) Hot Rolling: Steel billets are rolled at 1100-1250ºC. Annealing: Conducted at780-850ºCto relieve stress and restore ductility. Pickling: Removes oxide scale to achieve a bright surface. Cold Rolling: Further reduces thickness and improves surface precision/hardness. Surface Treatment: 2B, BA, polishing, or brushing as required. Application Fields 1. Home Appliance Industry Induction cooktop panels(accounting for ~60% market share): Perfectly matches high-temperature oxidation resistance and electromagnetic properties. Refrigerator/freezer panels, dishwasher liners. Oven liners, microwave components. 2. Architectural Decoration Curtain walls, decorative trim, elevator interiors. Ceilings, door/window frames. 3. Automotive Industry Body trim strips, grilles. Exhaust system components. Sensor elements (utilizing magnetic properties). 4. Kitchenware & Food Contact Kitchen range hoods, tableware (for dry environments). Complies withGB 4806.9-2023 food contact standard. Comparison with Other Stainless Steels

430 provides higher cost-performance
Limitations Poor resistance to chloride corrosion, unsuitable for high-salt environments (e.g., coastal areas). Prone to rusting in humid environments, limited to dry conditions. Limited high-temperature stability; long-term use above 600ºC may cause embrittlement due to grain coarsening. Selection Recommendations Suitable Scenarios: Indoor decoration, home appliance casings, and otherdry environmentapplications. Projects requiringcost-effectivenesswith moderate corrosion resistance. Products demandingthermal conductivity(e.g., radiator components). Applications utilizingmagnetic properties(e.g., induction heating elements). Unsuitable Scenarios: Outdoor high-humidity,salt spray environments(e.g., coastal buildings). Long-term exposure to strong corrosive media such as acids, alkalis, or salts. Structural components operating continuously above 600ºC. Summary 430 stainless steel strip stands out as an ideal choice for dry environment applications due to its cost-effectiveness, excellent workability, and thermal performance. If your project requires the aesthetics and durability of stainless steel within a budget, without exposure to high humidity or strong corrosion, 430 stainless steel strip is a highly cost-effective solution.
