China SUS 304 stainless steel wire mesh is a widely used industrial screening and filtration material. The term “SUS 304” refers to the Japanese Industrial Standard (JIS) designation for the same alloy as AISI 304 – an austenitic stainless steel containing 18% chromium and 8% nickel. Chinese manufacturers produce vast quantities of SUS 304 wire mesh, adhering to international quality standards while offering competitive pricing. This article provides a detailed overview of its properties, common specifications, and key considerations for buyers.
SUS 304 is the standard 18/8 stainless steel. Its chemical composition includes:
| Element | Percentage (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 18.0 – 20.0 |
| Nickel (Ni) | 8.0 – 10.5 |
| Iron (Fe) | Balance |
This composition provides good corrosion resistance in atmospheric, fresh water, and mild chemical environments. It also offers excellent formability and weldability, making it suitable for weaving into various mesh patterns.
SUS 304 stainless steel wire mesh is available in a wide range of mesh counts, wire diameters, and weave types. The table below shows typical specifications:
| Mesh Count (per inch) | Wire Diameter (mm) | Opening Size (μm) | Open Area (%) | Typical Weave |
|---|---|---|---|---|
| 20 x 20 | 0.40 | 870 | 70 | Plain |
| 40 x 40 | 0.25 | 385 | 58 | Plain |
| 60 x 60 | 0.15 | 273 | 55 | Plain |
| 80 x 80 | 0.12 | 197 | 48 | Plain |
| 100 x 100 | 0.10 | 154 | 45 | Plain |
| 120 x 120 | 0.0635 | 148 | 45 | Plain |
| 200 x 200 | 0.053 | 74 | 34 | Plain |
| 325 x 325 | 0.045 | 37 | 25 | Plain |
For finer filtration, Dutch weaves (Plain Dutch or Twilled Dutch) are also available in SUS 304, achieving absolute micron ratings from 5 μm to 150 μm.
Filtration: Water treatment, chemical processing, oil and fuel filtration.
Screening: Sizing and separating aggregates, powders, and granules in mining, food, and pharmaceutical industries.
Protection: Machine guards, safety screens, animal enclosures, and window screens.
Architectural: Decorative facades, balustrades, and ceiling panels.
When sourcing from China, buyers should:
Verify material grade – Request a Material Test Report (MTR) confirming the chemical composition meets SUS 304 standards.
Check dimensional accuracy – Ensure mesh count and wire diameter conform to the specified tolerances (typically ±2% for mesh count, ±5% for wire diameter).
Inspect packaging – Quality suppliers use moisture-proof paper and wooden cases for export.
Request samples – Always test a production sample before bulk orders.
Q1: Is SUS 304 the same as AISI 304?
A: Yes. SUS is the JIS designation, while AISI is the American standard. Both refer to the same 18/8 stainless steel alloy.
Q2: Can SUS 304 wire mesh be used outdoors?
A: Yes, for most outdoor environments. However, in coastal areas with high salt exposure, SUS 316 is recommended for better chloride resistance.
Q3: What is the maximum temperature for SUS 304 mesh?
A: Continuous service up to 550°C (intermittent up to 800°C). For prolonged high-temperature exposure, consider 310 stainless steel.
China SUS 304 stainless steel wire mesh offers a reliable and cost-effective solution for countless industrial applications. By partnering with a qualified supplier like Anping Milesen Metal Net Products Co., Ltd., buyers can obtain certified SUS 304 mesh with consistent quality and precise specifications.
