430 stainless steel strip introduction
430 stainless steel is a ferritic stainless steel, because of its good corrosion resistance, formability and cost effectiveness, widely used in household appliances, decoration, automotive and other fields. Compared with austenitic stainless steel (such as 304), 430 stainless steel does not contain nickel, so the cost is lower, but it is slightly lower in corrosion resistance and welding performance.
Chemical composition of 430 Stainless Steel Strips (typical value) :
- Carbon (C) : ≤0.12%
- Silicon (Si) : ≤1.00%
- Manganese (Mn) : ≤1.00%
- Phosphorus (P) : ≤0.040%
- Sulfur (S) : ≤0.030%
- Chromium (Cr) : 16.0-18.0%
Mechanical properties of 430 Stainless Steel Strips:
- Tensile strength: ≥450 MPa
- Yield strength: ≥205 MPa
- Elongation: ≥22%
- Hardness: ≤183 HB (Brinell hardness)
Physical properties of 430 Stainless Steel Strip:
- Density: 7.70 g/cm³
- Melting point: 1425-1510℃
- Thermal expansion coefficient: 10.4μm /m·℃ (20-100℃)

Surface of 430 Stainless Steel Strip
The surface state of 430 stainless steel belt is diverse, common are:
- 2B surface: After cold rolling, heat treatment, pickling and passivation treatment, the surface is smooth and reflective.
- BA surface: bright annealed surface, with high gloss, close to mirror effect.
- NO.1 Surface: After hot rolling, heat treatment and pickling treatment, the surface is rough.
- NO.4 Surface: After polishing, the surface is fine matte, often used for decorative purposes.
- specification
430 stainless steel Strip has a wide range of specifications, common sizes are as follows:
- Thickness: 0.03mm-3.0mm (can be customized).
- Width: 10mm-1000mm (can be customized)
- Length: Usually in roll shape, the length is customized according to customer requirements.
Application field
430 stainless steel tape because of its low cost, good formability, widely used in the following fields:
- Home appliance industry: washing machine inner tube, microwave oven shell, refrigerator panel, etc.
- Architectural decoration: elevator decorative board, interior decoration strip, door and window frame, etc.
- Automotive industry: exhaust pipes, decorative strips, fasteners, etc.
- Kitchenware industry: tableware, kitchenware, sink, etc.
- Electronic products: electronic components housing, shielding cover, etc.
430 stainless steel belt is an economical and practical ferritic stainless steel, suitable for occasions where corrosion resistance is not required. Its surface states are diverse, the specifications are flexible, widely used in household appliances, decoration, automotive and other fields. The selection must be based on application scenarios, performance requirements, and market availability.
