SS 304 Grade Stainless Steel Wire

The Crazy Wire Company are long established as Europe’s preferred suppliers of top quality ss 304 Grade stainless steel wire. We have enormous stock levels at all times, as we use this wire to weave our marine grade woven mesh products.

The ss 304 grade stainless steel is a high-quality product designed to meet the diverse needs of a variety of industries. This wire is made from stainless steel 304, which has excellent corrosion resistance and durability, and is one of the most widely used stainless steel grades. The 0.3mm (29AWG) diameter provides the right balance between strength and flexibility. Even in environments with high moisture and chemical exposure, the use of SS 304 ensures the wire’s resistance to oxidation and corrosion. Because of this, it is especially suitable for industries like food and beverage processing, water treatment plants, and other sectors that require both hygiene and longevity. Besides its robust physical properties, the wire’s smooth surface reduces friction, which can be beneficial in manufacturing and machinery operations. Additionally, its resistance to high temperatures makes it useful in a variety of settings.

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:

  • Diameter -0.3mm (300 Micron – 29 AWG)
  • Ohms/ft – 10.09

FAQs About This Wire

How Does SS 304 Grade Stainless Steel Wire Perform In Cold Environments?

SS 304 Grade Stainless Steel Wire performs admirably in cold environments. The molecular structure of stainless steel, particularly the SS 304 grade, allows it to retain its mechanical and physical properties even at sub-zero temperatures. Unlike some materials that can become brittle or compromised in freezing conditions, SS 304 maintains its ductility and strength. It does not show any significant changes in terms of brittleness until extremely cold temperatures, far below typical environmental conditions. As a result, this makes it a preferred choice for applications in cold regions or those that require refrigeration or freezing, ensuring durability and reliability without any substantial degradation in performance. Additionally, SS 304’s resistance to corrosion remains uncompromised in these colder settings, providing long-lasting utility and minimal maintenance needs.

Does SS 304 Grade Stainless Steel Wire Have Any Allergic Reactions When In Contact With Skin?

As a result of its hypoallergenic properties, SS 304 Grade Stainless Steel Wire is widely used in medical instruments, appliances, and jewelry. The chemical composition of stainless steel 304 makes allergic reactions very rare as it does not react with the body’s chemistry. Some people might be sensitive to nickel, which is present in many stainless steel grades, but most people do not experience allergic reactions when SS 304 grade stainless steel is in contact with their skin. Since SS 304 is one of the safest metals and alloys when it comes to skin contact, it is commonly used in applications such as watch bands or body piercings that involve prolonged contact with skin. Although it’s always a good idea to monitor for any signs of irritation or sensitivity, especially if an individual has known skin sensitivities or allergies.

What Are The Primary Elements/Alloys In SS 304 Grade Stainless Steel?

SS 304 Grade Stainless Steel, commonly referred to as A2 stainless steel or 18/8 stainless steel, is one of the most widely used grades of stainless steel. Its name “18/8” is derived from its chemical composition, which roughly includes:

  1. Chromium (Cr): Approximately 18%
  2. Nickel (Ni): Approximately 8%
  3. Carbon (C): Up to 0.08%
  4. Manganese (Mn): Up to 2%
  5. Silicon (Si): Up to 1%
  6. Phosphorus (P): Up to 0.045%
  7. Sulfur (S): Up to 0.03%
  8. Iron (Fe): The balance, making up the majority of the alloy.

These elements combine to give SS 304 its characteristic properties, including corrosion resistance, formability, and durability. The Chromium content offers the corrosion resistance, while Nickel adds to both the corrosion resistance and the austenitic structure of the steel, providing good formability and making it non-magnetic. The Carbon content is kept low to minimise the risk of carbide precipitation during welding. This can reduce the material’s resistance to intergranular corrosion.
