Anping County Boli Hardware Wiremesh Products Factory is proud to present our premium Duplex Stainless Steel Wire Mesh 1.4462, engineered for demanding industrial environments. With a wire diameter of 0.3 mm and a mesh count of 200 (aperture 1 mm), this mesh delivers exceptional strength, corrosion resistance, and precise filtration. As a manufacturer established in 1998, we combine decades of experience with advanced production techniques to offer you a product that stands up to extreme conditions while maintaining long service life.
This duplex stainless steel mesh is the ideal choice for applications where both high mechanical strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking are required. The 1.4462 (UNS S31803 / S32205) grade offers nearly double the yield strength of standard 304 or 316 stainless steel, making it suitable for aggressive media and high-pressure environments. Whether you need it for chemical filtration, offshore oil and gas, marine equipment, or architectural facades, our mesh delivers consistent performance.

Frequently Asked Questions (FAQ)
-
What is the difference between 1.4462 and 316L stainless steel mesh?
Duplex 1.4462 offers about twice the yield strength of 316L, plus better resistance to chloride stress corrosion cracking. It is preferred in harsh environments like offshore and chemical processing. -
Can this mesh be used for fine liquid filtration?
Yes, with 200 mesh (0.074 mm opening after wire deduction), it captures particles down to ~75 microns. For finer filtration, we can supply higher mesh counts. -
Is the mesh supplied in rolls or sheets?
Standard supply is in rolls. We can also cut into sheets or custom shapes per your request. Minimum order quantity may apply for custom sizes. -
What is the maximum width available?
Our standard weaving width is up to 2 meters. Wider widths up to 3 meters are available on special order, depending on weave type. -
Does the mesh come with any surface treatment?
The mesh is supplied in a cleaned, oil-free condition. Annealing, pickling, or passivation can be done as optional treatments. -
How do you ensure the mesh quality?
We perform visual inspection, dimensional checks, and tensile testing on each batch. A mill test certificate is available upon request. -
What is the lead time for bulk orders?
Typical lead time is 15–25 working days after order confirmation, depending on quantity and specifications. Urgent orders can be expedited. -
Can I get a sample before placing a large order?
Yes, we provide free samples (you pay shipping). Contact our sales team with your requirements.
