CBIES AUTOMOTIVE 45# side impact door beams have high strength, good plasticity, and toughness. After the drawing and annealing management, the elongation of the car door beams is higher and better. When the side door is hit, the door impact beam with high strength and good elongation, can greatly reduce the deformation of the side door, and improve the passive safety of the car.
Pickling hot-formed high-strength steel 22MnB5 is one of the highest-strength materials used in the car body. It is mainly used in car door impact beams and reinforcement plates, windshield pillar reinforcement plates, and other automotive safety components, which have both high strength and good toughness.
Processing Flow
Non-oxygen annealing is the heat treatment of steel tubes under vacuum conditions. Because there is no oxygen and no reaction with iron in the vacuum state, the surface of steel tubes has no oxide skin and the surface finish is bright and white. But the precision steel pipe produced by traditional annealing has a black surface and oxide skin.
