Applications of EN10149-2 S355MC Steel
Automotive Manufacturing:
Passenger Vehicles: Used in components such as anti-collision beams, chassis subframes, and seat slide rails, leveraging high strength to enhance safety performance while reducing energy consumption through lightweight design. For example, a certain vehicle model achieved a 15% weight reduction and a 20% improvement in impact resistance after adopting S355MC.
Commercial Vehicles: Frame longitudinal beams, cross members, and chassis supports are formed into complex integrated structures through cold forming to meet load-bearing requirements. For instance, the load-bearing capacity of a towing hook bracket increased by 30% after using this material.
Special-Purpose Vehicles: Refrigerated truck carriage frameworks and container floor supports are compatible with bending and roll forming processes, with surface coatings providing over 10 years of corrosion resistance.
Construction Machinery:
Core Components: Components subjected to alternating loads and impact loads, such as excavator booms, dipper arms, and crane jib auxiliary supports, benefit from its high strength and fatigue resistance to extend service life. For example, the boom life of a certain excavator model increased from 5,000 hours to 8,000 hours after adopting S355MC.
Hydraulic Systems: Hydraulic support tubes and equipment conveyance pipelines balance high strength and forming precision, meeting subsequent processing requirements.
Architecture and Infrastructure:
Steel Structures: High-rise building wind-resistant columns and large-span spatial structures (e.g., stadium roof trusses) utilize its high strength to reduce structural self-weight. For example, the roof truss of a certain international airport terminal adopted S355MC straight-seam pipes with a diameter of 406 mm and a wall thickness of 12 mm, achieving a single-span span of 120 meters.
Temporary Facilities: Construction temporary supports and movable housing frameworks offer easy assembly and disassembly, with strength meeting temporary load-bearing requirements. For example, temporary shelters in an earthquake-stricken area achieved a wind resistance rating of Level 12 after adopting this material.
New Energy Sector:
Wind Power Generation: Internal support structures for towers and main beams of photovoltaic brackets leverage its low-temperature toughness (stable operation at -40°C) to adapt to extreme environments. According to statistics, the demand for steel pipes for wind power increased by 23% year-on-year in 2024, with S355MC accounting for over 60% of the material composition.
Energy Storage Equipment: Battery enclosure frames adopting this material significantly improve collision safety.
Logistics and Transportation:
Warehouse Racking: High strength accommodates stacked loads, with cold-formed surfaces being flat and easy to assemble. For example, the load-bearing capacity of racks in a certain logistics center increased from 5 tons per layer to 8 tons per layer after adopting S355MC.
Logistics Turnover Boxes: Frame structures achieve complex shapes through deep drawing and bending, reducing welding steps and lowering production costs.
