Carbon spring wire is a type of metal wire used for various applications in the manufacturing industry. It is commonly used for springs and other types of applications requiring a material with superior strength and durability. The advantages of carbon spring wire include its high tensile strength, high elasticity, excellent corrosion resistance, and low cost.
Its high tensile strength makes it ideal for use in springs, as it can withstand the large forces exerted on them when compressed or stretched. This makes carbon spring wire an excellent choice for use in automotive and aerospace applications, as it is able to resist fatigue and extreme temperatures.
The high elasticity of carbon spring wire also makes it an ideal choice for shock absorbers, as it can withstand sudden impacts without breaking. This makes it a great choice for use in suspension systems, or any application that requires a shock-absorbing material.
Additionally, carbon spring wire provides excellent corrosion resistance due to its unique chemical composition. This makes it perfect for use in marine applications, as well as in areas where moisture or salt are present. The low cost of carbon spring wire also makes it a popular option for manufacturers looking to reduce costs without sacrificing quality.
When the steel wire enters the field, it should be accepted in batches. Each batch is 3t, and each batch is composed of steel wires of the same grade, shape and size, and delivery status. Take one tensile sample from each plate, 5% of each batch but not less than 5 plates, and take one repeated bending sample from each plate. Check the appearance and size of the wire coil by coil. There shall be no cracks, thorns, splits, mechanical damage, iron oxide scale and oil stains on the surface of the steel wire. 10% of the number of coils in each batch of steel wire shall be arbitrarily selected, and no less than 6 coils shall be selected from each end of each coil of steel wire.
