The 0.75mm 316L medical/marine grade stainless steel round wire is a versatile and durable product designed to meet various industrial and commercial needs. High-quality 316L stainless steel makes this wire excellent for rugged environments, as it is known to withstand corrosion and oxidation. A 0.75mm diameter ensures a fine balance between flexibility and strength, making it an ideal choice for precision applications. The wire comes on a 333g spool, which provides ample material for extensive use.

Stainless steel wire is especially useful in medical applications because of its biocompatibility, ensuring safety when in contact with human tissue, vital for surgical tools, implants, and braces. Its outstanding resistance to saltwater corrosion makes it a great choice for marine rigging, lashing, and structural applications. As a result of its strength and durability, wire is a go-to choice for jewelry making. It offers a hypoallergenic and long-lasting material for creating intricate designs.

Specification of this product:

  • Diameter – 0.75mm (750 Micron – 21 AWG)
  • Spool Size – 333g (Approx. 70 Metres)

We also offer the SS316L grade as flat wire too if required.

FAQs About This Wire

Can 0.75mm Wire Be Welded Or Soldered Easily?

  1. Welding: For welding such thin wire, precision methods like TIG (Tungsten Inert Gas) welding are recommended. TIG welding allows for greater control over the heat and the weld pool, which is crucial for preventing burn-through on thin materials. However, it requires skill and experience to weld thin wires successfully.
  2. Soldering: Soldering 0.75mm stainless steel wire is also possible but can be tricky. Stainless steel doesn’t easily accept solder due to its oxide layer, so a specialised flux is needed to remove this layer and allow the solder to bond. Additionally, using a solder that is specifically formulated for stainless steel is recommended.
  3. Preparation and Equipment: For both welding and soldering, proper surface preparation is crucial. The wire should be clean and free from any contaminants. Additionally, the right equipment and consumables (like appropriate welding rods or solder and flux for stainless steel) are essential for a successful join.
  4. Expertise: Both processes require a certain level of expertise. If you’re not experienced in welding or soldering, especially with materials like 316L stainless steel, it’s advisable to seek professional assistance.

Would 0.75mm Wire Resist Corrosion In Marine Environments?

The 0.75mm wire made with 316L stainless steel is extremely corrosion resistant in marine environments. 316L stainless steel is highly valued for its corrosion resistance, particularly against chloride ions found in seawater, which are prevalent in the environment. The low carbon content of 316L stainless steel minimises carbide precipitation during welding, preserving its corrosion resistance. In marine environments, components such as molybdenum, nickel, and chromium contribute significantly to its resistance to corrosion. Upon the wire’s surface, these elements form a passive layer that protects it from corrosive elements. Its durability is further enhanced by the exceptionally resilient nature of this protective layer, which can reform if damaged. Because of this, the 0.75mm 316L stainless steel wire maintains its strength and integrity even under the humid, saline, and fluctuating conditions found in marine environments. It is ideal for marine applications that require both strength and corrosion resistance, like rigging, lashing, etc.
