SS304 Wire Stainless Steel

The Crazy Wire Company are long established as Europe’s preferred suppliers of top quality SS304 wire stainless steel. We have enormous stock levels at all times, as we use this wire to weave our marine grade woven mesh products.

Stainless steel 304 wire has a diameter of 0.38mm, equivalent to 27AWG, and is a premium-quality wire. This stainless steel wire is manufactured from SS304 grade stainless steel for excellent corrosion resistance, strength, and durability. Its SS304 grade ensures not only resistance to oxidation and corrosion but also structural integrity under a variety of conditions. The thickness and strength of this wire make it suitable for a wide range of applications. Intricate jewelry designs, household repairs, and professional projects all benefit from its consistency and dependability. In addition, the stainless steel 304 wire has improved longevity, reducing the need for frequent replacements and providing better value over time. Due to its temperature resistance, it is also suitable for tasks that involve heat exposure.

We provide a comprehensive range of sizes tailored to meet diverse needs. The wire diameters range from a delicate 0.08mm up to a more robust 0.87mm. These sizes correspond to American Wire Gauge (AWG) standards from 40AWG down to 20AWG. To assist with electrical applications, it’s noteworthy that our wire resistances vary from 252.17 Ωm at the finest size, decreasing to 1.2 Ωm as the wire diameter increases.

Specification of this product:

FAQs About This Wire

How Do I Store Unused SS304 Wire?

Storing unused SS304 wire properly ensures it remains in good condition and retains its physical properties.

  1. Clean the Wire: Before storing, ensure that the wire is clean and free from any dirt, grease, or other contaminants. Wipe it with a soft cloth, and if needed, use a mild detergent or cleaning agent suitable for stainless steel.
  2. Coil or Spool: If your SS304 wire is long, coil it neatly or wind it onto a spool. This helps prevent kinks and tangling.
  3. Dry Environment: Store the SS304 wire in a dry place. While SS304 is resistant to corrosion, prolonged exposure to moisture can lead to minimal surface rusting.
  4. Avoid Chemical Exposure: Store the wire away from chemicals, especially chlorine or bleach, as these can corrode stainless steel.
  5. Temperature: Try to store it in a temperature-stable environment. Extreme temperature fluctuations can affect the metal’s properties.
  6. Plastic or Cloth Bag: Put the wire inside a plastic or cloth bag to keep out dust and contaminants. This also helps in case there’s any moisture, as it provides an extra layer of protection.
  7. Labeling: If you have multiple types of wire, label them to easily identify the SS304 wire when needed.
  8. Away from Other Metals: If possible, store the SS304 wire separately from other metals, especially if those metals are known to be reactive.
  9. Regular Checks: Every few months, inspect the wire to ensure there’s no surface rust or other issues. If there’s any rust, it can usually be cleaned with a mild abrasive.

How Long Does SS304 Wire Last Before Needing Replacement?

The longevity of SS304 wire largely depends on its application, environment, and maintenance. There are several types of stainless steel available, but SS304 is known for its corrosion resistance and durability. The SS304 wire can last for several years without significant degradation in most conditions, where it is not exposed to harsh chemicals or extreme wear and tear. It may never need to be replaced for applications in controlled environments, such as indoor fixtures or light-duty crafts. However, in harsher conditions, such as marine environments where the wire is exposed to saltwater, or in industrial applications where it is constantly stressed, its lifespan may be reduced. Regular inspection is essential. A wire should be replaced if it shows signs of excessive wear, corrosion, or structural deformities. Maintenance, such as cleaning and ensuring it’s free of contaminants, can further extend its life.

How Does SS304 Wire React To Prolonged Exposure To Sunlight?

SS304 wire, when exposed to prolonged sunlight, remains largely unaffected in terms of its structural integrity. Ultraviolet (UV) radiation from the sun does not have a deteriorative effect on stainless steel as it might on some other materials, like certain plastics. However, there’s an indirect effect to consider. Sunlight can cause an increase in temperature, and while SS304 has good resistance to heat, in extremely hot conditions or in continuous direct sunlight, the wire might become hot to the touch. Furthermore, if the SS304 wire is in an environment with contaminants, sunlight can accelerate the oxidation process when combined with these contaminants, although SS304’s natural resistance to corrosion minimises this risk. It’s also worth noting that while the sun won’t degrade the wire itself, any coatings or finishes applied to the SS304 wire might fade or deteriorate with extended UV exposure.
