Hot-rolled Steel Coils for Automotive
This series of products include beam steel, wheel steel, axle steel, axle housing steel and other structure steels etc. In addition,these steels have good toughness and bending performance.
They also exhibit good welding performance and a homogeneous microstructure. Thus,they can well meet the requirements of commercial vehicle weight and high fatigue strength.
In order to meet the increasingly high requirements for safety, weight reduction, energy conservation, and environmental protection, we have developed many high-strength steel grades to meet various specific requirements, as follows:
- The low-alloy and high-strength steel of yield strength 550 ～ 700MPa can be used in automobile beams, carriages, drive axles and other automobile structure parts with good formability and welding performance.
- The wheel steel of tensile strength 450 ～ 650MPa.
- The high-strength axle housing steel.
- The high-strength drive axle steel.
