Deqing Linyuan Metal Products Co., Ltd. has launched 72A high-carbon steel wire with a specification of 1.8mm. Relying on its core advantages of "moderate hardness, strong toughness and excellent wear resistance", it provides stable and reliable material solutions for the precision demands of multiple fields such as industrial manufacturing, home life and creative creation.
Raw materials and processes: Ensure quality from the source
This high-carbon steel wire uses high-carbon steel strips with a purity of over 99.5% as the base material. Through precise composition control, the carbon content is stabilized at 0.70%-0.75% (referred to as the "golden ratio"), which not only ensures the basic hardness of the steel wire but also avoids the problem of easy brittle fracture of high-carbon materials. At the same time, the content of elements such as manganese (0.60%-0.90%) and silicon is strictly controlled. After spectral detection and verification, the distribution of each element is uniform, ensuring the consistency of steel wire performance from the source.
After continuous casting and rolling, the high-carbon steel strip has a fine internal metallographic structure free of impurities, pores, cracks and other defects, providing high-quality billets for subsequent processing. Precisely formed through multiple cold drawing processes, the 1.8mm diameter tolerance is strictly controlled within ±0.02mm. It not only meets the load requirements of high-intensity scenarios but also has moderate plasticity, facilitating secondary processing such as bending and winding. Tests show that its tensile strength reaches 1500-1800 mpa and it is not easy to break when subjected to large tensile forces. After professional fatigue testing, it can withstand over 100,000 repeated stresses without obvious deformation, and its fatigue resistance far exceeds that of ordinary low-carbon steel wire.
Balanced performance: Combining wear resistance and shaping
The Brinell hardness of HB220-250 brought by grade 72A enables the steel wire to not only precisely maintain its shape (like the rebound tension of a precision spring), but also possess the toughness to resist stress brittle fracture. After phosphating treatment on the surface, a dense protective film is formed, with wear resistance increased by over 30%. It is more wear-resistant when rubbing against other components, thus extending the service life of the accessories. Meanwhile, the surface finish reaches Ra≤0.8μm, free of burrs and scratches, reducing the wear and tear on the mold during processing.
Multi-scenario adaptation: Covering industrial, home, and creative fields
In the industrial field: It is an ideal material for precision springs (such as valve springs and instrument return springs), and can stably rebound under high-pressure conditions. It can also be used for the clips and hooks of transmission mechanisms, ensuring long-term smooth operation with its wear resistance.
Home scenarios: It can be made into high-strength clotheslines and storage racks, with a load capacity of over 50kg and not prone to deformation, meeting the daily storage and drying needs.
Creative creation: Artists often bend it into the framework of sculptures and DIY jewelry stands, which not only ensures the stability of the shape but also enables the realization of detailed creativity through plasticity.
Flexible services and protective packaging: In line with market demands
The product offers flexible specification services, with a length range of 50 meters to 1000 meters to choose from. It can also be packaged in rolls as required. Each roll is protected by a double layer of moisture-proof kraft paper and plastic film on the outside to prevent rust or damage during transportation and storage, fully ensuring quality and delivery experience.
The launch of this new product demonstrates Deqing Linyuan Metal's strength in material research and development as well as production processes, and also brings high-quality new options for material applications in various precision scenarios of different fields.
