Commercial Vehicles Beam Steels

Beam structure bears the main loads of the commercial vehicles. The beam steels must show good strength and toughness,  and high fatigue property. From the forming methods, commercial vehicles beams can be divided into stamping beam, rolling  beam, and welding beam. For stamping beam and rolling beam, the steels should have high cold forming performance. For  welding beam, the steels should show good weldability. Baosteel beam steels mainly include microalloyed high strength beam steels and ultra high strength beam steels, with a  highest yield strength of 960MPa.

Mechanical Properties

Steel Characteristics

High strength beam steels reach the highest yield strength  level of 700MPa. The steels not only have good purity,  excellent toughness, and good fatigue performance, but also  have excellent performance of cold forming and welding.  The steels are suitable for stamping beam, rolling beam, and  welding beam. Ultra high strength beam steels reach the highest yield  strength level of 960MPa, delivered by heat treatment. The  steels show high purity, excellent toughness, good fatigue  performance, good weldability, excellent flflatness and surface  quality. The steels are suitable for welding beam.
