Automobile girder steel is a kind of low alloy hot-rolled steel plate with thickness of 2.5-12.0 mm for manufacturing automobile girder (longitudinal beam and cross beam). Due to the complex shape of automobile girder, good stamping performance is required in addition to high strength and cold bending performance for automobile girder steel. The A633 grade D carbon steel material, medium thick and heavy steel plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on.

Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. A633 grade D carbon steel material, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
