SS304 Welding Wire

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

As a high-quality stainless steel welding wire with a thickness of 0.08mm (40AWG), SS304 welding wire ensures precision and durability for a wide range of welding applications. Due to its stainless steel grade 304 (SS304) composition, it offers significant corrosion resistance, making it ideal for long-term projects. Additionally, the thickness of 0.08mm enables users to perform detailed welding tasks, especially when producing intricate or smaller parts. Aside from its primary use in welding, SS304 welding wire is good for utilising across a wide range of industries, including automotive and construction. SS304 is known for its corrosion resistance as well as its robustness. It’s often used in projects that require both strength and elegance.

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 -0.08mm (80 Micron – 40 AWG)

FAQs About This Wire

Can SS304 Welding Wire Be Used For Automotive Applications?

Yes. Due to its outstanding properties, SS304 welding wire is ideal for automotive applications. It’s made from stainless steel grade 304, which offers corrosion resistance and strength, ensuring durable and long-lasting welds. As automotive parts and structures are often exposed to varying weather conditions, road salt, and other corrosive elements, corrosion resistance of SS304 is especially important. Designed to weld intricate and detailed tasks, it is particularly useful in automotive manufacturing and repair work due to its 0.08mm (20AWG) thickness. The robustness of SS304 welding wire ensures that the welds can withstand the stresses and strains typical of automotive applications. Whether it’s for bodywork, exhaust systems, or engine components, SS304 welding wire delivers the reliability and performance automotive applications require.

What Is The Maximum Tensile Strength Of SS304 Welding Wire?

The tensile strength of a material refers to the maximum amount of tensile (pulling) stress that it can withstand without failure. For SS304 stainless steel, the typical tensile strength ranges between 515 to 690 megapascals (MPa) or about 75,000 to 100,000 pounds per square inch (psi). However, it’s important to note that the exact tensile strength of SS304 welding wire can vary. This is based on the specific manufacturing process, any treatments the wire undergoes, and its precise chemical composition. It’s always advisable to consult the product specifications or the manufacturer’s datasheet to get the exact tensile strength for a particular batch or brand of SS304 welding wire. The high tensile strength of SS304 makes it a favorable choice for applications demanding strength and durability.

What Are The Main Benefits Of Using SS304 Welding Wire?

The main benefits of using SS304 welding wire encompass a combination of material properties and application versatility.

  1. Corrosion Resistance: SS304 stainless steel is inherently resistant to corrosion, making welds performed with this wire durable, especially in environments prone to rust and oxidation.
  2. Strength and Durability: The wire boasts a strong tensile strength, ensuring that the welds are robust and long-lasting.
  3. Precision Welding: Given its 0.08mm (40AWG) thickness, SS304 welding wire is particularly suitable for intricate and detailed welding tasks, enabling precision in applications.
  4. Temperature Resistance: SS304 can withstand high temperatures, making it suitable for tasks that might involve heat or are exposed to hot conditions.
  5. Aesthetic Appeal: Welds made with SS304 often have a cleaner, shinier finish, and adding an aesthetic appeal to the end product. This is especially valued in visible components or applications.
  6. Versatility: Due to its properties, SS304 welding wire is versatile and finds uses in a range of industries, from automotive to construction and more.
  7. Non-magnetic Nature: After welding, SS304 typically remains non-magnetic, which can be a crucial factor for certain applications.
  8. Formability: SS304 offers good formability, meaning it can be easily shaped without compromising its integrity.
  9. Cost-Effective: While SS304 offers premium quality, it remains cost-effective for many applications, striking a balance between performance and cost.
