Meta Description: Discover 430 stainless steel fittings with unbeatable mirror finish capability. Cost-effective, magnetic, and ideal for food-grade, decorative, and architectural applications.
Introduction
430 Stainless Steel Fittings are known for their remarkable magnetic properties, superior formability, and cost-effectiveness, making them the preferred choice for decorative and food-grade applications. Compared to 304 stainless steel, 430 fittings offer a 40–60% cost savings, while maintaining a similar appearance after polishing. These fittings excel in both aesthetic and functional performance, making them ideal for a range of industries, from food processing to luxury kitchen equipment.
With their outstanding mirror polishing ability (including 8K finish), 430 stainless steel fittings provide a level of visual appeal that is unmatched by other materials, allowing manufacturers to achieve a premium look at a fraction of the cost. In addition to their exceptional polishability, 430 stainless steel offers good corrosion resistance and oxidation resistance up to 870°C, making it suitable for both interior and exterior applications.
Thanks to its high magnetic permeability, 430 stainless steel fittings are perfect for use in food-grade applications where magnetically attractable components are necessary for easy separation in industrial processes. These fittings are also widely used in architectural and decorative applications where aesthetics are a priority. From elevator interiors to kitchen appliances, 430 stainless steel fittings offer the ideal balance of strength, durability, and affordability.

| Elongation (%) | ≥16 |
| Hardness (Rockwell B) | 80–90 |
430 stainless steel fittings offer moderate strength and ductility, making them suitable for a wide range of general-purpose applications. Their good elongation ensures they can withstand slight deformation without breaking, while their moderate hardness provides good resistance to wear.
Physical Properties
| Property | Value |
|---|---|
| Density (g/cm³) | 7.75 |
| Thermal Expansion (10⁻⁶/°C) | 10.2 |
| Thermal Conductivity (W/m·K) | 25.0 |
| Magnetic | Yes |
430 stainless steel fittings are magnetic, unlike 304 stainless steel. This property is essential in applications such as magnetic separation and food processing, where magnetic properties are required. The material also has a moderate thermal expansion and thermal conductivity, making it suitable for high-temperature applications.
430 vs 304 vs 201 vs 441 vs 409 Fittings Comparison
| Property | 430 Stainless Steel | 304 Stainless Steel | 201 Stainless Steel | 441 Stainless Steel | 409 Stainless Steel |
|---|---|---|---|---|---|
| Cost | Low | High | Low | Moderate | Very Low |
| Corrosion Resistance | Moderate | Excellent | Poor | Good | Fair |
| Polishability | Excellent | Excellent | Good | Good | Moderate |
| Magnetic | Yes | No | Yes | Yes | Yes |
| Formability | Good | Good | Good | Excellent | Good |
| Max Temperature (°C) | 870 | 925 | 800 | 870 | 800 |
430 stainless steel fittings provide an excellent balance of cost, corrosion resistance, and polishability. They are significantly cheaper than 304 stainless steel but still offer good corrosion resistance and magnetic properties. Compared to 201 stainless steel, 430 offers better corrosion resistance and polishability, making it the superior choice for many decorative and food-grade applications.
