Where is it mainly used in passenger vehicles?
Front and rear bumper beams (high strength + energy absorption)
Chassis subframe/control arms (lightweight + rigidity)
Seat rails/door bumper bars (safety structure)
Core applications in commercial vehicles (heavy trucks/light trucks)?
Frame longitudinal beams/crossbeams (main load-bearing, S355MC/JR)
Cargo box pillars/frames/supports (load-bearing + torsional resistance)
Towing hooks/suspension brackets (high strength + impact resistance)
Applications in special-purpose vehicles (refrigerated/van-type)?
Cargo box frame/container support: good cold bending forming, high strength, weight reduction.
Why choose S355 instead of Q235?
50% higher strength, 15-20% weight reduction
Superior fatigue resistance/toughness/weldability
Meets automotive lightweighting + safety + load-bearing requirements
What are the chassis advantages of S355MC? High strength + excellent cold forming properties enable one-piece molding of complex parts, reducing welding, weight, and increasing rigidity.
