SS 304 stainless steel wire mesh – where “SS” stands for stainless steel – is the most commonly specified woven wire product worldwide. Its balance of corrosion resistance, strength, and affordability makes it suitable for thousands of applications, from simple insect screens to critical filtration elements. This article provides a technical overview of SS 304 wire mesh, including its mechanical properties, weave options, and selection guidelines.
| Property | Typical Value |
|---|---|
| Tensile strength (annealed) | 515 – 620 MPa |
| Yield strength (0.2% offset) | 205 – 310 MPa |
| Elongation (in 50 mm) | 40 – 60% |
| Hardness (Brinell) | ≤ 201 HB |
| Density | 7.93 g/cm³ |
| Modulus of elasticity | 193 GPa |
| Melting range | 1400 – 1450°C |
| Maximum continuous service temperature (air) | 550°C |
These properties allow SS 304 mesh to withstand significant mechanical stress, vibration, and thermal cycling without permanent deformation.
| Weave Type | Characteristics | Typical Mesh Range |
|---|---|---|
| Plain weave | Simplest, stable, good flow | 1 – 500 mesh |
| Twill weave | Diagonal pattern, stronger, higher flow | 30 – 400 mesh |
| Plain Dutch weave | Dense, fine filtration | 20 – 200 mesh (warp) |
| Twilled Dutch weave | Very dense, ultra‑fine filtration | 30 – 325 mesh (warp) |
| Application | Recommended SS 304 Mesh |
|---|---|
| Coarse sifting (aggregates, coal) | 4 – 20 mesh, plain weave, 1.0 – 2.5 mm wire |
| General industrial screening | 30 – 100 mesh, plain weave, 0.15 – 0.4 mm wire |
| Fine powder sieving (flour, pigments) | 120 – 200 mesh, plain weave, 0.05 – 0.07 mm wire |
| Liquid filtration (water, coolants) | 60 – 200 mesh, plain or twill |
| High‑precision filtration (chemicals, oils) | Dutch weave, 10 – 150 μm absolute |
| Decorative / architectural | 4 – 40 mesh, plain weave, polished finish |
SS 304 offers excellent resistance to:
Fresh water and humidity
Most organic chemicals
Mild acids (e.g., acetic, citric)
Alkaline solutions
Limited resistance to:
Chlorides (saltwater, bleach) – pitting risk
Strong reducing acids (e.g., hydrochloric, sulfuric)
Marine atmospheres (316 is preferred)
Q1: What is the difference between SS 304 and SS 316 wire mesh?
A: SS 316 contains 2–3% molybdenum, which significantly improves resistance to pitting and crevice corrosion in chloride environments. For general use, SS 304 is sufficient and more economical.
Q2: Can SS 304 wire mesh be used in food contact applications?
A: Yes. SS 304 is FDA‑approved for food contact. It is widely used in food processing sieves, filters, and conveyor belts.
Q3: How is SS 304 wire mesh cleaned after use?
A: For dry particles – brushing or air blow. For wet contaminants – backflushing, ultrasonic cleaning, or soaking in mild detergent. Avoid strong acids or chloride‑based cleaners.
Q4: What is the typical shelf life of SS 304 wire mesh?
A: Indefinite if stored in a dry, indoor environment. Outdoor storage should avoid direct contact with the ground and be covered.
SS 304 stainless steel wire mesh is a versatile, reliable, and cost‑effective material for countless industrial and commercial applications.
