High-quality stainless steel round wire 304 grade is designed for various applications across a wide range of industries. The 0.15mm diameter (equivalent to 34AWG) offers a fine balance between strength and flexibility. 304 grade stainless steel is known for its corrosion resistance, ensuring durability and longevity even in environments exposed to moisture and other potentially corrosive elements. Because of its strength, flexibility, and wear and tear resistance, it is the ideal material for projects requiring a combination of strength, flexibility, and durability.

Furthermore, the 304 grade stainless steel composition ensures that the wire retains its form and function over time without degrading. This makes it suitable for both short-term and long-term uses. From intricate jewelry-making, electronic components, and precision engineering projects to general household repairs and crafts, stainless steel round wire 304 grade can be used for a variety of projects. Choosing this wire means reducing the frequency of replacements and optimising long-term costs by using a reliable and resilient product.

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 -0.15mm (150 Micron – 34 AWG)

FAQs About This Wire

Is SS Round Wire 304 Grade Resistant to Saltwater Corrosion?

The 304 grade of SS (Stainless Steel) Round Wire is corrosion-resistant, even when exposed to saltwater. It’s important to note that 304 stainless steel is not as resistant to saltwater corrosion than 316 grade stainless steel, despite its good corrosion resistance. Molybdenum is added to the 316 grade, which makes it more resistant to chloride corrosion in marine and saltwater environments. The 316 grade might be a better choice if the wire will be used in a marine environment or exposed to saltwater continuously. When exposed occasionally or in limited quantities, 304 grade will suffice, but periodically rinsing or cleaning it will prolong its lifespan.

What Is The Expected Lifespan of SS Round Wire 304 Grade in Regular Use?

The expected lifespan of SS Round Wire 304 Grade can vary widely based on its application and the conditions to which it’s exposed. In regular use, under typical conditions without excessive wear, moisture, or corrosive substances, 304-grade stainless steel wire can last for several decades. Its inherent corrosion resistance and durability mean that it maintains its structural integrity and appearance over time. However, factors like exposure to aggressive chemicals, saltwater, high levels of pollution, and frequent physical abrasion can shorten its lifespan. Regular maintenance, such as cleaning to remove contaminants or debris, can help extend its life. It’s essential to evaluate the specific environment and usage patterns to get a precise estimate, but with proper care, SS Round Wire 304 Grade remains a long-lasting and reliable choice in many applications.

How Resistant Is SS Round Wire 304 Grade to Oxidation?

SS Round Wire 304 Grade is highly resistant to oxidation, which is one of its defining attributes. The chromium content in the 304-grade stainless steel reacts with oxygen in the atmosphere to form a thin, passive layer of chromium oxide. This layer effectively protects the underlying metal from further oxidation or rusting. As a result, 304-grade stainless steel doesn’t easily rust, tarnish, or corrode when exposed to air or moisture. Even if this protective layer gets scratched or damaged, the metal will “heal” itself. This is because the chromium present will react with oxygen and reform this protective barrier.

However, while it provides excellent resistance to oxidation in most environments, prolonged exposure to certain chemicals or high salinity environments, like constant exposure to sea air or saltwater, can challenge its resistance. For such conditions, higher grades such as 316, with its added molybdenum content, may be more appropriate due to enhanced corrosion resistance.
