430 Magnetic Stainless Steel Mesh

430 Stainless Steel wire mesh (UNS S43000, AISI 430, UNS S43000,  1.4016,  1Cr17) is a ferritic & magnetic stainless steel weave mesh screen. Unlike the austenitic grades we've discussed previously (904L, 310S, 309), 430 is magnetic in all conditions.

Typical Chemical Composition:

(Note: Contains negligible Nickel, which is the primary driver of cost and magnetism in stainless steels.)

Common Mesh Forms; 430 Stainless steel Woven Wire Mesh

· Weave types: Plain weave, Twill weave,Crimped

· Mesh count: 2 mesh ~ 200 mesh

· Wire diameter: 0.05 mm – 3.0 mm

· Shape: Roll, sheet, disc, filter element

Properties of 430 Filter Mesh

· Magnetic: Strong magnetic permeability, can be attracted by magnets.

· Corrosion resistance: Good in atmosphere, fresh water, steam, mild alkaline & acidic environments; lower than 304/316L.

· Heat resistance: Good oxidation resistance at medium temperature.

· Cost-effective: Lower price than austenitic 304/316L stainless steel.

· Weldability: Generally not recommended for heavy welding; easy to crack.

Common Applications

· Magnetic Separation: Used as a protective screen or filter media in conjunction with magnetic rods or separators to remove ferrous contaminants from powders and liquids (e.g., in food processing, plastics, recycling).

· Speakers and Grilles:Mesh for speaker covers or protective grilles where the mesh needs to be magnetically permeable.

· Automotive Trim:Decorative mesh applications where magnetism aids in installation or retention.

· Kitchenware: Filters for commercial dishwashers, strainers, and baskets where mild corrosion resistance and low cost are required.

· Battery Applications: Current collectors or separators in certain types of batteries.
