Tire Cord Steel Wire Rod

Tire cord steel wire rod is a high-end special raw material developed by Wongsteel (Beijing Yijing Technology) for the tire manufacturing and rubber product industries. It covers two series: **LX72A/LX82A** and **C72DA/C82DA**, with specifications covering 5.5mm and 6.5mm, strictly following national standards such as GB/T 27691 and GB/T 24242.2, and can be customized according to the technical agreement for supply. As the key material for producing core skeleton materials such as tire radial steel wire and bead wire, it is widely used in high-end rubber product fields such as automotive tires, heavy-duty truck tires, engineering machinery tires, and aircraft tires.

**LX72A/LX82A series** focuses on extreme cord processing performance, with core advantages of **small decarburization layer, few inclusions, and high sorbite rate**. It has extremely high steel purity, stable and uniform composition, excellent tensile strength and comprehensive mechanical properties, as well as outstanding plasticity and toughness. It can adapt to ultra-high-speed multi-pass wire drawing processes. The processed radial tire steel wire has high strength, good toughness and excellent fatigue resistance, which can provide stable skeleton support for tires, greatly improving the load-bearing capacity, impact resistance and service life of tires, making it the preferred raw material for passenger car tires and high-performance tires.

**C72DA/C82DA series** focuses on the processing of bead wire and special steel wires, with core features of **high sorbite rate, high purity, and excellent comprehensive mechanical properties**. It achieves further optimization in composition control and tissue uniformity, and also has the quality advantages of small decarburization layer and few inclusions. It can stably process high-strength bead wire, hose wire and other products, providing reliable strength support for tire bead, rubber hose and other components, adapting to the stringent requirements of heavy-duty scenarios such as heavy-duty truck tires and engineering machinery tires.

Both wire rods undergo strict steelmaking, rolling and full-process quality control, ensuring the purity and performance consistency of the wire rod from the source, and meeting the extreme requirements of the tire industry for high-end steel wire raw materials. Wongsteel (Beijing Yijing Technology) can provide accurate material matching and customized supply services according to customers' tire types, steel wire specifications and processing technologies, and is equipped with professional technical support and comprehensive after-sales guarantee, helping tire manufacturing enterprises improve product quality and market competitiveness.
