Product Introduction

65Mn spring steel wire has a carbon content of 0.62%-0.70%, a manganese content of 0.90%-1.20%, a tensile strength of 980-1275MPa, a yield ratio of ≥0.85, an elastic limit of 800MPa after quenching and tempering, a rebound rate of over 95%, and is suitable for fatigue resistance in a wide temperature range of -30℃ to 150℃ (500,000 bends without breaking). After bluing/galvanizing for corrosion protection, it is specially used for automobile suspension springs, pneumatic tool valve springs, precision instrument compression springs and high-elasticity fishing reels. With the synergistic effect of high-carbon alloy reinforcement and manganese element solid solution at the grain boundaries, it has both ultra-high elastic reserve and anti-creep stability, making it the core wire material for heavy-load high-frequency working springs.

Advantages of Carbon Steel Wire

1. High strength: Carbon steel wire has high strength and is an excellent structural material. It can withstand large tensile forces and maintain its shape. These characteristics make carbon steel wire widely used in construction, machinery manufacturing, automobile manufacturing and other fields.

2. Good plasticity and workability: Carbon steel wire is easy to process and form. It can be processed into various shapes and sizes through cold stamping, cold rolling, drawing and other processes. This makes carbon steel wire widely used in metal products, electrical appliance manufacturing, electronic equipment and other industries.

3. Strong corrosion resistance: Since the surface of carbon steel wire has been treated with galvanizing or copper plating, its corrosion resistance is greatly enhanced. This makes carbon steel wire widely used in construction, shipbuilding, chemical industry and other fields.

4. Good electrical conductivity: Carbon steel wire has excellent electrical conductivity and can be used to manufacture electrical equipment such as wires, cables, and motors. It can also be used for wires and connecting wires of electronic products, such as mobile phones, computers, etc.

5. Good wear resistance: After special treatment, the surface of carbon steel wire has strong wear resistance. This makes carbon steel wire widely used in the manufacturing of cutting tools, abrasives and other fields.

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Applications of Carbon Steel Wire

1. Bridges and large buildings

Carbon steel wire is used as the main cable of cable-stayed bridges or prestressed steel bars to bear the core tension of kilometer-level spans. Its high strength and galvanized coating can resist seawater corrosion and dynamic loads, ensuring the life of the structure for a hundred years. In high-rise buildings, carbon steel wire bundles improve the crack resistance of concrete, achieve lightweight design, and reduce the burden on the foundation.

2. Automobile industry

Suspension springs are made of high-carbon steel wire, which has a hardness of HRC58-62 after quenching and can withstand millions of high-frequency vibrations; transmission chains and gears are made of wear-resistant carbon steel wire, with a friction coefficient as low as 0.05, ensuring power transmission efficiency. The electric vehicle battery pack fixing bracket also uses a lightweight carbon steel wire frame, taking into account both strength and energy efficiency.

3. Mechanical manufacturing

The saw blade base is made of cold-drawn carbon steel wire with a tensile strength of over 2000MPa, and it can achieve precise cutting of metal plates with high-speed steel teeth; the spring clamp is processed by shape memory, and can maintain a positioning accuracy of 0.1mm in an environment of -40℃ to 150℃, which is widely used in CNC machine tools and automated production lines.

4. Energy transmission

UHV transmission towers use galvanized carbon steel wire pull wires, with a single breaking force of 120kN and a wind deflection angle of over 30 degrees; the anchor chain of offshore wind power platforms is made of carburized steel wire, which is 5 times more resistant to seawater corrosion than ordinary steel wire, ensuring the stability of floating foundations in 15-meter waves.

5. Safety protection

The explosion-proof wire mesh adopts a double-layer interwoven structure, which can intercept 5kg TNT equivalent explosion shock waves; the bank vault door spring lock has a built-in carbon steel wire torsion spring, which has no fatigue failure after 100,000 opening and closing tests, and cooperates with the biometric recognition system to achieve millisecond-level response protection.

6. Daily civilian use

Bicycle spokes are made of high-carbon steel wire, which can withstand a vertical load of 80kg at a diameter of 1.5mm; medical orthopedic braces use 3D woven carbon steel mesh to increase air permeability by 40% while maintaining joint support, becoming the mainstream solution for sports injury rehabilitation.
