Classification of 430 Stainless Steel Coils
430 stainless steel coils include two main types: 430 stainless steel and 430F stainless steel. However, there are several different classifications of these coils based on factors such as composition, surface brightness, or origin. Below are two important classifications to consider when selecting their specifications:
Composition of 430 Stainless Steel Coils
The main chemical components of 430 stainless steel coils include Cr, Fe, Si, Mn, and P. These elements influence the basic properties of the coil. A small change in these components can result in a coil with different characteristics.
-
430 Stainless Steel Coil: Similar to other types of 430 stainless steel, this coil primarily contains 17% chromium and 0.75% nickel. However, the content of these two elements is relatively high, while other elements are negligible. 430 stainless steel is cost-effective, but its corrosion resistance properties are not as outstanding.
-
430F Stainless Steel Coil: Based on its composition, 430F stainless steel lacks the sulfur element, which impacts its inherent corrosion resistance. This change also affects its ability to resist pitting and grooves on the surface.
Surface of 430 Stainless Steel Coils
The corrosion resistance of 430 stainless steel coils reaches its maximum when the coil is polished or highly polished. This is a key factor in affirming the aesthetic value of this material.
-
430 Stainless Steel Coil BA Surface: To achieve the BA finish on a 430 stainless steel coil, physical polishing is required. The BA surface has a mirror-like shine, making it highly suitable for household items.
-
430 Stainless Steel Coil 2B Surface: The 2B surface is more affordable than the BA surface. It has a color similar to chrome and reflects light well, especially in thinner coils. Compared to 2D stainless steel, the 2B finish is more commonly used due to its better corrosion resistance.
-
430 Stainless Steel Coil No.1 Surface: The No.1 surface is the first stage of the polishing process. It has a rough, earthy color, formed after heating to remove the black oxide layer on the surface. This is the initial stage of the polishing process.
-
430 Stainless Steel Coil HL Surface: HL stands for Hairline, meaning hairline scratches. The surface of HL coils has long, fine stripes that are polished. The production process may involve re-polishing to enhance or repair the scratches. However, most HL surfaces feature light scratches and are not overly prominent when in use.
-
430 Stainless Steel Coil Dull Surface: Of all the surface finishes, the Dull finish is the most matte. 430 stainless steel with a Dull finish also has a rougher surface, which can be seen as a distinctive feature for interior and exterior decoration applications.
Size of 430 Stainless Steel Coils
Most 430 stainless steel coils are produced with specific size parameters. These can be either standard sizes with permissible tolerances or custom sizes based on individual orders. The thickness, length, width, and weight of the coil will affect its pricing. Measurements before production or after shipment are guaranteed to be accurate. Excessive material deviations may result in differences in the finished product. Below are the most commonly used sizes:
Thickness of 430 Stainless Steel Coils
430 stainless steel coils have the thinnest gauge among all types of stainless steel products. Common thicknesses include:
-
-
0.1 – 1mm
-
2mm
-
3mm
-
5mm
-
6mm
-
8mm
-
10mm
-
Width of 430 Stainless Steel Coils
Most customers seeking 430 stainless steel coils will typically find standard widths available. However, there are custom orders for specific applications. The requested width should not deviate too much from the standard measurements. Below are the most common coil widths:
-
-
1000mm
-
1220mm
-
1500mm
-
1550mm
-
Length of 430 Stainless Steel Coils
-
-
1000mm
-
2000mm
-
2440mm
-
6000mm
-
Weight of 430 Stainless Steel Coils
The weight of the coil is calculated based on the accurate measurements of its length, width, and thickness:
Weight (kg) = Width (m) x Length (m) x Thickness (mm) x 7.93 (g/m³)
Applications of 430 Stainless Steel Coils in Interior Design:
One of the most common applications of 430 stainless steel coils is in products like cabinets, tables, chairs, and railings. Comparable to other materials, 430 stainless steel coils are favored for both interior and exterior decoration. In particular, 430 coils with No.4 and HL finishes are most widely used in this sector.
Applications of 430 Stainless Steel Coils in Industrial Equipment Manufacturing:
430 stainless steel is used in the production of railway vehicles and transportation equipment for various industries. 430 coils are also a popular material in the coal mining industry due to their high heat resistance.
Applications of 430 Stainless Steel Coils in the Chemical Industry:
430 coils are extensively used to prevent corrosion at critical weld joints. The quality of weld joints is crucial in the shipbuilding industry, making 430 stainless steel an essential material in both this sector and the chemical industry.
| Comparison Items | 200 Series (201) | 300 Series (304 as a representative) | 400 Series (430 as a representative) |
|---|---|---|---|
| Chemical Composition | Chromium (Cr) 16% – 18%, manganese (Mn) 5.5% – 7.5%, nickel (Ni) 3.5% – 5.5%, nitrogen (N) ≤0.25% | Chromium (Cr) 18% – 20%, nickel (Ni) 8% – 10.5%, low carbon | Chromium (Cr) 16% – 18%, low carbon, ferrite structure |
| Tensile Strength (MPa) | ≥520 | ≥515 | ≥450 |
| Elongation (%) | ≥40 | ≥40 | ≥22 |
| Corrosion Resistance | Moderate corrosion resistance, suitable for less corrosive environments. Prone to rusting in humid or corrosive conditions compared to 300 series. | Good general corrosion resistance, suitable for general atmosphere, fresh water and other environments, relatively weak tolerance to chloride ions | Fair corrosion resistance, better than carbon steel but inferior to 300 series. Susceptible to pitting corrosion in chloride-rich environments. |
| Magnetic Properties | Weakly magnetic due to its alloy composition | Non-magnetic in the annealed state, may become slightly magnetic under certain processing conditions | Magnetic |
| Cost | Relatively low, due to lower nickel content and relatively simple composition | Moderate, as a widely used and reliable grade | Relatively low, similar to 200 series in terms of cost, but with different performance characteristics |
| Application Fields | Interior decoration, low-end kitchenware, some decorative trims in buildings where corrosion resistance requirements are not high | Kitchen utensils, building decoration, general industrial components and other daily fields | Appliance housings, automotive trim, some food processing equipment where non-magnetic properties are not required and moderate corrosion resistance suffices |
