430 stainless steel wire mesh is a cost-effective and reliable metal mesh product manufactured by our company, using high-quality 430 ferritic stainless steel wires. As a ferritic stainless steel, 430 is characterized by its chromium-rich composition (without nickel), offering a balance of corrosion resistance, formability, and affordability. It is an ideal choice for applications where moderate corrosion resistance is required, and cost efficiency is a key consideration, making it widely used in various industrial and commercial fields.
Material Characteristics
- Moderate Corrosion Resistance: 430 stainless steel contains approximately 16-18% chromium, which forms a protective oxide layer on the surface of the woven mesh. This layer provides resistance to corrosion in mild environments, such as atmospheric conditions, fresh water, and some non-aggressive chemicals. While it is not as resistant to harsh corrosive media (like high chloride solutions or strong acids) as austenitic stainless steels (e.g., 304 or 316), it performs well in dry or slightly humid environments, making it suitable for many general-purpose applications.
- Good Mechanical Properties: 430 stainless steel wire mesh exhibits decent tensile strength and ductility, allowing for easy fabrication, cutting, and forming. It can be bent, welded (with appropriate techniques), and shaped into various forms without significant loss of structural integrity, providing flexibility in installation and application.
- Magnetic Properties: Unlike austenitic stainless steels, 430 is magnetic, which makes it suitable for applications where magnetic properties are required, such as in magnetic separation systems or components that need to interact with magnetic fields.
- Heat Resistance: It can withstand moderate temperatures, up to around 600°C in continuous use, making it suitable for applications involving low to medium heat, such as in oven racks, heat shields for non-critical components, and general-purpose high-temperature screening.
Structural Characteristics
- Uniform and Stable Mesh: Our 430 stainless steel wire mesh is produced using precise weaving techniques, ensuring uniform mesh size, consistent opening area, and reliable performance in screening, filtering, and separation tasks. The interwoven wires form a stable structure that resists deformation under normal mechanical stress, ensuring long-term functionality.
- Cost-Effective Design: The use of 430 stainless steel, which lacks nickel, makes the woven mesh more affordable compared to nickel-containing stainless steels. This cost advantage does not compromise basic performance, making it a practical choice for budget-conscious applications that do not require extreme corrosion resistance.
- Smooth Surface and Easy Maintenance: The surface of 430 stainless steel wire mesh is smooth, reducing the adhesion of dust, dirt, and light contaminants. It can be easily cleaned with water, mild detergents, or simple wiping, ensuring hassle-free maintenance in everyday use.
- Customizable Specifications: To meet diverse application needs, we offer a range of customization options for 430 stainless steel wire mesh. This includes varying mesh counts (from coarse meshes for heavy-duty screening to finer meshes for light filtration), wire diameters, mesh shapes (square, rectangular), and sheet sizes. Our team works closely with customers to deliver tailored solutions that fit their specific requirements.

Standards & Compliance
430 stainless steel wire mesh is a ferritic, nickel-free grade complying with ASTM A240 and corresponding to UNS S43000. Because it is ferritic and magnetic, it is the standard choice for magnetic separation and iron-removal screening in food and sugar processing.
FAQ
What is 430 stainless steel wire mesh?
430 stainless steel wire mesh is a ferritic, chromium-containing (16–18% Cr) stainless steel woven mesh. It is nickel-free, more cost-effective than 304, and — unlike austenitic grades — is magnetic.
Is 430 stainless steel wire mesh magnetic?
Yes. 430 is a ferritic stainless steel, so it is magnetic, whereas austenitic grades such as 304 and 316 are non-magnetic. This makes 430 suitable for magnetic separation and iron-removal screening.
What is the difference between 430 and 304 wire mesh?
430 is ferritic, magnetic and nickel-free, with moderate corrosion resistance and a lower cost. 304 is austenitic, non-magnetic and contains 8–10.5% nickel, with better corrosion resistance. Choose 430 when you need magnetism or lower cost; choose 304 for general corrosion resistance.
What is 430 wire mesh used for?
430 wire mesh is widely used in food and sugar processing for magnetic iron-removal screening, in grain sorting screens, automotive exhaust components, kitchen equipment and appliance grilles, where its magnetism and lower cost are advantages.
Is 430 stainless steel wire mesh food grade?
Yes. 430 is commonly used in food processing applications, especially for dry-material sorting, baking equipment and sugar-industry magnetic filtration, where its nickel-free composition and magnetic property are required.
What temperature can 430 wire mesh withstand?
430 wire mesh withstands continuous use up to about 600°C, making it suitable for low-to-medium heat applications such as oven racks, heat shields and general high-temperature screening.
