High-Temperature Resistant 321 Stainless Steel Wire Mesh ASME SA240

SS 321 wire mesh is made from stainless steel grade 321, a titanium-stabilized alloy in the 300-series family. SS 321 mesh combines the corrosion resistance of 304 stainless steel with superior performance at elevated temperatures up to ~850 °C.

Material Standard
SS 321 wire mesh is manufactured from stainless steel grade 321, meeting standards ASTM A240, ASTM A479 and ASME SA240.

Features
SS 321 mesh offers excellent oxidation resistance up to ~850 °C, high creep strength, and good toughness under thermal cycling. Compared with 304 stainless steel, 321 grade stainless steel mesh maintains superior stability at elevated temperatures, suitable for filtration and structural screening.

Applications
SS 321 wire mesh is widely used in petrochemical, aerospace, heat-treatment, filtration and drying equipment. With good mechanical strength, dimensional stability and resistance to scaling, SS 321 wire mesh is a reliable choice for demanding industrial filtration and screening applications.

Selection Tips of SS Mesh Materials
Choose 304 SS for standard corrosion resistance at lower cost.
Choose 316 SS where chloride or acid resistance is critical.
Choose 321 SS for high-temperature filtration and thermal cycling applications.
