1. Low-alloy hot-rolled steel plates with a thickness of 2.5- 12.0mm are used to manufacture automobile cross beams (longitudinal beams and cross beams). Because of the complex shape of automobile cross beam, it requires not only high strength and cold bending performance, but also good stamping performance.

2. The automobile beam slab is mainly used for manufacturing automobile longitudinal beams, cross beams, front and rear axles, bumpers and other structural parts. Its thickness is generally 4.0-8.0 mm, which is a kind of steel with large demand and high performance requirements in automobile structural steel plates.
