With the increasing awareness for safety, energy saving and  environment protection, there is an urge for high strength  steel for automotive. Hot-rolled high strength steel sheets,  which are widely used in wheel, beam, carriage, axle, drive  shaft, chassis, suspension and other important parts, can  provide great potential for weight reduction.

Baosteel began to develop hot-rolled high strength steel  for automobile in 2004 and successfully developed various  types of high strength steel which can satisfy difffferent  performance requirements, such as:

① 550~700MPa low alloy high strength steels in yield  strength with good formability and weldability, which  can be used in beam, carriage, drive shaft and other  structural parts of automobiles.

② 450~650MPa wheel steels in tensile strength.

③ 600MPa grade steel for axle housing in tensile  strength.

④ Advanced high strength steel (440~780MPa high  hole expansion steels, 580 and 780MPa dual-phase  steels, 580 and 780MPa TRIP steels）with good  formability and high anti-fatigue property, which is  applicable to parts with complex shapes.

⑤ Heat treated ultra high strength steel and wear  resistant steel

Baosteel adopts advanced smelting technology to gain  pure steel with low inclusion. Precisely controlled rolling and  controlled cooling technologies are used to obtain expected  microstructures to meet application requirements.

Baosteel hot-rolled high strength steels for automobiles are  widely used in car and truck factories, auto parts factories  and car tuning shops. High strength steel sheets make  it possible to reduce auto body weight, which thereby  contributes to improved manufacturing cost.
