304 stainless steel woven wire 120 mesh is one of the most popular industrial screening products. The number “120” refers to 120 openings per linear inch (approximately 47 openings per centimeter). This mesh count offers a good balance between particle retention and flow rate, making it a versatile choice for many applications. This article provides a complete technical overview of 304 stainless steel 120 mesh woven wire.
For a standard 120 mesh plain weave cloth using 304 stainless steel, typical parameters are:
| Parameter | Typical Value |
|---|---|
| Mesh count (warp × weft) | 120 × 120 |
| Wire diameter | 0.0635 mm (0.0025 inches) |
| Opening size (aperture) | 148 microns (approx.) |
| Open area percentage | ~ 45% |
| Weight (approx.) | 0.45 kg/m² |
| Width availability | 1 m, 1.2 m, 1.5 m (custom slit) |
Note: Values can vary slightly between manufacturers; always check the supplier’s datasheet.
The use of 304 stainless steel provides good corrosion resistance against fresh water, mild chemicals, and atmospheric conditions. It is not recommended for direct contact with strong chlorides (e.g., seawater, bleach) or highly acidic environments.
Particle analysis: Used in test sieves for powder classification (e.g., flour, pigments, metal powders).
Liquid filtration: Filtering coolants, lubricants, and low‑viscosity process water.
Air and gas venting: As a protective screen to prevent insect or dust ingress.
Printing industry: Screen printing of textiles and graphics (120 mesh is a standard grade for many ink types).
Food processing: Sieving of grains, spices, and dry ingredients.
The 120 mesh opening of approximately 148 microns means it will retain most particles larger than 150 microns. For applications requiring removal of smaller particles, a higher mesh count (e.g., 200, 325) is needed. Conversely, for higher flow, a lower mesh count like 60 or 80 is used.
The 304 grade offers a maximum continuous operating temperature of around 550°C in air (though for long‑term use, 450°C is safer). At elevated temperatures, oxidation may occur, but the mechanical properties remain acceptable for many screening tasks.
Q1: What is the difference between 304 and 316 stainless steel in 120 mesh?
A: 316 contains molybdenum, which gives better resistance to pitting corrosion in saltwater and acidic environments. For general indoor or fresh water use, 304 is sufficient and more economical.
Q2: Can I weld 304 stainless steel 120 mesh?
A: Yes, but care is needed. Spot welding or TIG welding with fine control is possible. For large assemblies, mechanical clamping or framing is often easier.
Q3: How do I clean a 120 mesh screen?
A: For dry particles, brushing or compressed air works. For wet applications, backflushing with water or ultrasonic cleaning is effective. Avoid steel brushes which can damage the weave.
304 stainless steel woven wire 120 mesh is a reliable, cost‑effective screening medium for a wide range of industrial and laboratory tasks. Its 148‑micron aperture provides fine yet high‑flow separation. When sourcing, ensure the supplier provides accurate wire diameter and opening size data. Anping Milesen Metal Net Products Co., Ltd. offers 120 mesh in 304 and 316 grades, cut to size or in full rolls.
