Our 904L Stainless Steel Wire Mesh is engineered from ultra-low carbon, high-alloy austenitic stainless steel, specifically designed for the most demanding industrial environments. Combining high levels of nickel, chromium, and molybdenum with the strategic addition of copper, this premium mesh provides unmatched resistance to pitting, crevice corrosion, and severe chemical attacks, ensuring stability where standard grades fail.
Specifically optimized for high-chloride ion environments and strongly acidic media, 904L mesh serves as a critical component in high-end industrial filtration. While offering a higher initial investment than 304 or 316 grades, its exceptional durability significantly reduces downtime and maintenance frequency, delivering a lower total cost of ownership for petrochemical, pharmaceutical, and marine engineering applications.

| Comparison Factor | Grade 316L Mesh | Grade 904L Mesh |
|---|---|---|
| Initial Cost | Low to Moderate | High |
| Corrosion Resistance | Standard (Moderate) | Extreme (Superior) |
| Maintenance Cycle | Frequent Replacement | Long-term Stability |
| Acid Resistance | Basic Acids | Strong Sulfuric/Phosphoric |
| Total Operating Cost | Higher (due to downtime) | Lower (extended lifecycle) |
904L contains higher nickel, molybdenum, and added copper, which provides vastly superior resistance to sulfuric acid and chloride-induced pitting compared to 316L.
It is primarily used in petrochemicals, pharmaceutical processing, marine engineering, and environmental power systems where extreme corrosion resistance is mandatory.
Yes, 904L maintains excellent structural stability and corrosion resistance even under combined high-temperature and high-chloride conditions.
We offer mesh sizes from 2 to 400 mesh, wire diameters from 0.03mm to 1.8mm, and widths ranging from 0.5m up to 4.5m.
Absolutely. By significantly reducing the frequency of replacement and unplanned maintenance downtime, 904L reduces overall operating costs in harsh environments.
Yes, we maintain a large stock of Duplex (2205/2507), Hastelloy, Monel, Inconel, and other high-nickel alloy wire cloths.
