A Comprehensive Guide to 430 Stainless Steel Sheet in China
430 stainless steel sheet is a popular choice in various industries due to its unique properties and cost-effectiveness. Widely available from numerous suppliers across China, understanding its characteristics is crucial for selecting the right material for specific applications. This guide delves into the technical aspects, different types, and key considerations when sourcing 430 stainless steel sheet from Chinese manufacturers like those found on www.shuangjiustainless.com, www.stainless-sheets.com, www.metal-in-China.com, www.superstainlessalloy.com, and www.China-stainless-steel.com.
Understanding 430 Stainless Steel
430 stainless steel, also known as ferritic stainless steel, is primarily composed of chromium. Unlike austenitic grades (like 304), it contains minimal nickel. This composition gives it excellent resistance to corrosion and oxidation at elevated temperatures. Its ferritic nature makes it non-hardenable through heat treatment, but it offers good formability and maChinability. Many Chinese suppliers, such as those listed on www.metal-in-China.com, highlight these characteristics.
Technical Features of 430 Stainless Steel Sheet
The following table compares key technical features of 430 stainless steel sheet, information readily available from suppliers like www.superstainlessalloy.com.
| Feature | Value | Units |
|---|---|---|
| Tensile Strength | 450-620 | MPa |
| Yield Strength | 205-345 | MPa |
| Elongation | 18-25 | % |
| Hardness | 80-160 | HB |
| Density | 7.7 | g/cm³ |

Different Types of 430 Stainless Steel Sheet
Several variations of 430 stainless steel sheet exist, each suitable for different applications. The distinctions often lie in surface finish and manufacturing processes. Suppliers such as www.shuangjiustainless.com often offer a wide variety of these finishes.
| Type | Description | Surface Finish Examples | Applications |
|---|---|---|---|
| Cold Rolled | Rolled at room temperature, resulting in smoother surface and tighter tolerances. | 2B, BA, No. 4, Hairline | Decorative applications, appliances, automotive trim |
| Hot Rolled | Rolled at high temperatures, resulting in a rougher surface. | No. 1, pickled | Industrial applications, where surface finish is less critical |
| Annealed and Pickled | Heat treated to relieve stress and improve formability; then pickled to remove oxides. | 2B, BA | Applications requiring improved formability |
Choosing the Right 430 Stainless Steel Sheet
The selection process involves considering factors like the required mechanical properties, surface finish, and application. The desired thickness, width, and length are also important considerations, often customizable through many Chinese suppliers such as those on www.stainless-sheets.com. For example, thinner sheets are better suited for forming, while thicker ones provide greater strength and durability. The chosen surface finish impacts the aesthetic appeal and corrosion resistance.
Conclusion
430 stainless steel sheet offers a valuable combination of properties, making it a versatile material for numerous applications. Chinese manufacturers provide a wide range of options, from standard sizes and finishes to custom-made specifications. Understanding the technical aspects and different types of 430 stainless steel sheet allows for informed decision-making, ensuring the selection of the optimal material for each project.
