Round SS316 Wire

The Crazy Wire Company are long established as Europe’s preferred suppliers of top quality round SS316 wire. We have enormous stock levels at all times, as we use this wire to weave our marine grade woven mesh products.

The round SS316 wire, at 0.3mm (29 AWG), is a versatile product made from marine-grade stainless steel, known for its durability and corrosion resistance. The wire is ideal for marine applications such as boat rigging and fishing gear since it can withstand harsh saltwater conditions. The material is often used for railings and balustrades in construction and architecture, where it features both an aesthetic appeal and structural integrity. The thin diameter of this material and its strength make it an excellent choice for sleek, modern designs.

The round SS316 wire is popular in the DIY and crafting community for jewelry making and wire sculptures due to its ease of manipulation and tarnish resistance. Spring manufacturing, precision instruments, and machinery also benefit from its chemical resistance and high temperature resistance. Among its uses in the medical field, wire is employed for medical devices and implants due to its biocompatibility. As a multipurpose, reliable material, round SS316 wire can be used in a variety of sectors across a variety of industries.

FAQs About This Wire

Can 316 Stainless Steel Be Used For Wire Cutting?

Yes, 316 stainless steel can be used for wire cutting. 316 stainless steel is a type of austenitic stainless steel that contains molybdenum, which makes it more resistant to corrosion and pitting compared to other types of stainless steel. Additionally, its high nickel content provides good toughness, making it suitable for use in applications that require both strength and corrosion resistance, such as wire cutting. However, the specific conditions of the wire cutting process, such as the hardness and thickness of the wire, will affect the performance of the cutting tool and should be considered when selecting a cutting material.

What Is The Electrical Resistance Of 316 Stainless Wire?

The electrical resistance of 316 stainless steel wire depends on several factors, including its composition, temperature, and diameter. However, as a rough estimate, the electrical resistance of 316 stainless steel wire can be calculated using the formula:

R = ρ * L / A

where R is the electrical resistance, ρ is the electrical resistivity of the material, L is the length of the wire, and A is the cross-sectional area of the wire.

The electrical resistivity of 316 stainless steel is typically around 7.2 x 10^-8 ohm-meter. Therefore, the electrical resistance of a 10 cm long, 1 mm diameter wire made of 316 stainless steel would be approximately:

R = 7.2 x 10^-8 * 0.1 / (π * (0.5 * 10^-3)^2) = 7.2 x 10^-8 * 0.1 / 7.86 x 10^-7 = 0.009 ohms

This is just a rough estimate and the actual electrical resistance may vary slightly depending on the specific conditions of the wire.

Is 316 A Good Resistance Heating Wire?

Yes, 316 stainless steel can be a good resistance heating wire, due to its high resistance to corrosion and high temperature stability. It is commonly used as a heating element in various industrial and residential applications, such as heating water in boilers, electric ovens, and electric dryers.

The electrical resistance of 316 stainless steel makes it an efficient conductor of heat, and its high temperature stability ensures that it can withstand high temperatures without undergoing significant changes in its properties. Additionally, its resistance to corrosion makes it suitable for use in high-moisture environments where other materials might be subject to corrosion.

What Is A Soft Wire?

A soft wire is a wire that is flexible, pliable, and can be easily bent and shaped. Soft wire is typically made from materials with low hardness, such as copper, aluminum, and some alloys, and has a low modulus of elasticity, which means it can be stretched and deformed without breaking.

Soft wire is commonly used in applications where flexibility and ease of manipulation are important, such as electrical wiring, jewelry making, and craft projects. It is also used as a filler material in welding and brazing, as well as in the manufacture of springs and other elastic components.

The specific properties of a soft wire, such as its flexibility, tensile strength, and conductivity, can vary depending on the type of material it is made from. In general, soft wires are characterized by their ability to be easily bent and shaped, as well as their relatively low resistance to deformation.
